-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Summary Report Announcement ID: SUSE-SR:2010:007 Date: Tue, 30 Mar 2010 10:00:00 +0000 Cross-References: CVE-2008-6514, CVE-2008-7247, CVE-2009-1299 CVE-2009-2563, CVE-2009-2855, CVE-2009-3553 CVE-2009-4019, CVE-2009-4028, CVE-2009-4030 CVE-2009-4376, CVE-2009-4377, CVE-2009-4484 CVE-2010-0302, CVE-2010-0304, CVE-2010-0308 CVE-2010-0393, CVE-2010-0424, CVE-2010-0547 CVE-2010-0628, CVE-2010-0736, CVE-2010-0926 Content of this advisory: 1) Solved Security Vulnerabilities: - cifs-mount/samba - compiz-fusion-plugins-main - cron - cups - ethereal/wireshark - krb5 - mysql - pulseaudio - squid/squid3 - viewvc 2) Pending Vulnerabilities, Solutions, and Work-Arounds: none 3) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Solved Security Vulnerabilities To avoid flooding mailing lists with SUSE Security Announcements for minor issues, SUSE Security releases weekly summary reports for the low profile vulnerability fixes. The SUSE Security Summary Reports do not list or download URLs like the SUSE Security Announcements that are released for more severe vulnerabilities. Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update. - cifs-mount/samba With enabled "wide links" samba follows symbolic links on the server side, therefore allowing clients to overwrite arbitrary files (CVE-2010-0926). This update changes the default setting to have "wide links" disabled by default. The new default only works if "wide links" is not set explicitly in smb.conf. Due to a race condition in mount.cifs a local attacker could corrupt /etc/mtab if mount.cifs is installed setuid root. mount.cifs is not setuid root by default and it's not recommended to change that (CVE-2010-0547). Affected products: SLE 11, openSUSE 11.0-11.2 - compiz-fusion-plugins-main The expo plugin in Compiz Fusion allowed local users with physical access to bypass the screen-saver by just dragging it aside. (CVE-2008-6514: CVSS v2 Base Score: 6.2) Affected products: SLE 11, openSUSE 11.0-11.2 - cron This update of cron fixes a race condition in crontab that can be used to change the time-stamp of arbitrary files while editing the crontab entry. CVE-2010-0424: CVSS v2 Base Score: 3.6 Additionally the return value of initgroups() is verified now. Affected products: SLE 10 SP2+SP3 , SLE 11, openSUSE 11.0-11.2, Moblin 2.0-2.1 - cups lppasswd when running setuid or setgid still honors environment variables that specify the location of message files. Local attackers could exploit that to gather information by using crafted format strings (CVE-2010-0393). The previous fix for a use-after-free vulnerability (CVE-2009-3553) was incomplete (CVE-2010-0302). Affected products: SLE 11, openSUSE 11.0-11.2, Moblin 2.0-2.1 - ethereal/wireshark This update of ethereal fixes: - CVE-2009-4376: Remote attackers could potentially trigger a buffer overflow in the Daintree SNA file parser. - CVE-2009-4377: Specially crafted packets could cause the SMB and SMB2 dissector to crash wireshark. - CVE-2009-2563: Unspecified vulnerability in the Infiniband dissector allows remote attackers to cause a denial of service. - CVE-2010-0304: Several buffer overflows in the LWRES dissector. Affected products: SLES 9, SLE 10 SP2+SP3, SLE 11, openSUSE 11.0-11.2 - krb5 MITKRB5-SA-2010-002: unauthenticated remote attacker could cause a GSS-API application including the Kerberos administration daemon (kadmind) to crash. CVE-2010-0628 has been assigned to this issue. Affected products: openSUSE 11.2 - mysql - fixing various security issues (bnc#557669) - upstream #47320 - checking server certificates (CVE-2009-4028) - upstream #48291 - error handling in subqueries (CVE-2009-4019) - upstream #47780 - preserving null_value flag in GeomFromWKB() (CVE-2009-4019) - upstream #39277 - symlink behaviour fixed (CVE-2008-7247) - upstream #32167 - symlink behaviour refixed (CVE-2009-4030) - fixing remote buffer overflow (CVE-2009-4484) Affected products: SLE 10 SP2+SP3 - pulseaudio Due to a race condition in pulseaudio a local attacker could make pulseaudio change ownership and permissions of arbitrary files. The problem is only security relevant if pulseaudio is run in "system mode" which is not the case by default (CVE-2009-1299). Affected products: openSUSE 11.0-11.2 - squid/squid3 The following vulnerabilities have been fixed in squid: - CVE-2009-2855: DoS via special crafted auth header - CVE-2010-0308: DoS via invalid DoS header Affected products: SLES 9, SLE 10 SP2+SP3, SLE 11, openSUSE 11.0-11.2 - viewvc Query forms didn't escape user provided input, therefore allowing cross-site-scripting (XSS) attacks. CVE-2010-0736 has been assigned to this issue. Affected products: openSUSE 11.0-11.2 ______________________________________________________________________________ 2) Pending Vulnerabilities, Solutions, and Work-Arounds none ______________________________________________________________________________ 3) 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 containing 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 integrity of a package needs to be verified to ensure that it has not been tampered with. 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 included at the end of this announcement. - 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>. opensuse-security-announce@opensuse.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <opensuse-security-announce+subscribe@opensuse.org>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
