-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: kernel Announcement ID: SUSE-SA:2007:030 Date: Thu, 10 May 2007 11:00:00 +0000 Affected Products: SUSE LINUX 9.3 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2006-2936, CVE-2006-5749, CVE-2006-5753 CVE-2006-6106, CVE-2007-1357, CVE-2007-1592 Content of This Advisory: 1) Security Vulnerability Resolved: Linux kernel security update Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion This kernel update for SUSE Linux 9.3 fixes the following security problems: - CVE-2006-2936: The ftdi_sio driver allowed local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued. This requires this driver to be loaded, which only happens if such a device is plugged in. - CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver (net/bluetooth/cmtp/capi.c) in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via CAPI messages with a large value for the length of the (1) manu (manufacturer) or (2) serial (serial number) field. - CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux kernel does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash. - CVE-2006-5753: Unspecified vulnerability in the listxattr system call in Linux kernel, when a "bad inode" is present, allows local users to cause a denial of service (data corruption) and possibly gain privileges. - CVE-2007-1357: A denial of service problem against the AppleTalk protocol was fixed. A remote attacker in the same AppleTalk network segment could cause the machine to crash if it has AppleTalk protocol loaded. - CVE-2007-1592: A local user could affect a double-free of a ipv6 structure potentially causing a local denial of service attack. and the following non security bugs: - patches.suse/dynamic-timeslice: Updated to prevent an overflow leading to an oops when max_timeslice is set too high. [#222334] - patches.fixes/xfs-kern-28000a-buffer-unwritten-new: Set the buffer new flag on writes to unwritten XFS extents. This fixes a corruption in preallocated files on XFS [#237843] This is also the final SUSE Linux 9.3 kernel update. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes Please reboot the machine after installing the update. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/Intel-536ep-4.69-10.10.i586.rpm fdef0ae9ea3862c4e00f6994360872b8 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-bigsmp-2.6.11.4-21.17.i586.rpm 05597adee5633418de222195a7c40d44 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-bigsmp-nongpl-2.6.11.4-21.17.i586.rpm b636aa46448deece58538f8c1d3c5c4f ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-default-2.6.11.4-21.17.i586.rpm 3014be6caa536a7016ecff4ae44eeda7 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-default-nongpl-2.6.11.4-21.17.i586.rpm 860d232b71d75a7007f61fc77b032e66 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-smp-2.6.11.4-21.17.i586.rpm 54b07696cf8cb4f1d7d1b151739ee8b2 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-smp-nongpl-2.6.11.4-21.17.i586.rpm fa0e06f232d995a545be05118fc39609 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-source-2.6.11.4-21.17.i586.rpm af55f08914f29161bf614ca697dd5ff2 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-syms-2.6.11.4-21.17.i586.rpm fe767d1307cafe1c2baf2f03eefb05f2 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-um-2.6.11.4-21.17.i586.rpm 675dd328bd37afc957b2d73472b92087 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-um-nongpl-2.6.11.4-21.17.i586.rpm 8764dc69a3822dce8dd20f01a8c3e580 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-xen-2.6.11.4-21.17.i586.rpm edb465f61c4ddf94b57877e6b9cfa798 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/kernel-xen-nongpl-2.6.11.4-21.17.i586.rpm 7c719e3764ec9e958a99843ff93b750a ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/ltmodem-8.31a10-7.10.i586.rpm eade8681bd82bc76fbfa7a12bf5ee266 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/um-host-install-initrd-1.0-50.11.i586.rpm 851e597bcb8a238a26c1b27d76683132 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/um-host-kernel-2.6.11.4-21.17.i586.rpm a4b8d7eb58d5441ebfca5a8d483dc4e6 Platform Independent: SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/noarch/kernel-docs-2.6.11.4-21.17.noarch.rpm 8b3a50ba429e5a51ce78134fef94abf6 x86-64 Platform: SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-default-2.6.11.4-21.17.x86_64.rpm bf3d35dc8e67699723cb745f4e68007b ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-default-nongpl-2.6.11.4-21.17.x86_64.rpm fb2467dfb4090fb75d17b41007a39f02 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-smp-2.6.11.4-21.17.x86_64.rpm 2ecc43230b3a8c7f73a884d3a6262b23 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-smp-nongpl-2.6.11.4-21.17.x86_64.rpm d494ce918294e9b24bdbcd1975931cd8 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-source-2.6.11.4-21.17.x86_64.rpm bb7f69f9b81c5875fbebfccdb57c62af ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/kernel-syms-2.6.11.4-21.17.x86_64.rpm 3430571de7938b942cd3d2ea9bc01482 Sources: SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/Intel-536ep-4.69-10.10.src.rpm e99717e4aee96f92ce0091c5757b96e7 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-bigsmp-2.6.11.4-21.17.nosrc.rpm 5c69f6f12b62308a60ed8d9e176f89b5 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-default-2.6.11.4-21.17.nosrc.rpm 15b26cd8982d957b97fa4a42dbea6bb7 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-docs-2.6.11.4-21.17.src.rpm 118a3feff96d107ad250d038cbfb757f ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-smp-2.6.11.4-21.17.nosrc.rpm ddd99e90d4941ffeb9e58f47399111f4 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-source-2.6.11.4-21.17.src.rpm a036fc6a08f2e05ef8a74731d56b59dd ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-syms-2.6.11.4-21.17.src.rpm e2478089fd67694eedae37de1d65e673 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-um-2.6.11.4-21.17.nosrc.rpm 94e5039b8458613c0a6129ea9e2cf747 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/kernel-xen-2.6.11.4-21.17.nosrc.rpm 80b94b463592a6e2d6bbd87dd0a22548 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/ltmodem-8.31a10-7.10.src.rpm cddb366a8ae7195309671d545ca1c644 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/um-host-install-initrd-1.0-50.11.src.rpm 7a5d67be8e978660bb79f2b5eb61de33 ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. ______________________________________________________________________________ 6) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security@suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or RPM package: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build@suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> after you downloaded the file from a SUSE FTP server or its mirrors. Then compare the resulting md5sum with the one that is listed in the SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security@suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: opensuse-security@opensuse.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security+subscribe@opensuse.org>. suse-security-announce@suse.com - SUSE's announce-only mailing list.
