SUSE Security Summary Report
Announcement ID: SUSE-SR:2007:008 Date: Fri, 27 Apr 2007 14:00:00 +0000 Cross-References: CVE-2007-1349, CVE-2007-1463, CVE-2007-1464 CVE-2007-1667, CVE-2007-1797, CVE-2007-1841 CVE-2007-2231
Content of this advisory: 1) Solved Security Vulnerabilities: - ipsec-tools remote denial of service - inkscape format string problems - rarpd minor denial of service - ImageMagick/GraphicsMagick integer overflows - mod_perl denial of service - dovecot path traversal 2) Pending Vulnerabilities, Solutions, and Work-Arounds: - Month of PHP bugs 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 md5 sums 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.
- ipsec-tools remote denial of service
A bug in the IKE daemon "racoon" allowed remote attackers to shut down established tunnels (CVE-2007-1841).
This problem was fixed for all SUSE Linux based distributions.
- inkscape format string problems
Several format string problems where fixed in inkscape.
CVE-2007-1463: A format string vulnerability in Inkscape allows user-assisted remote attackers to execute arbitrary code via format string specifiers in a URI, which is not properly handled by certain dialogs.
CVE-2007-1464: Format string vulnerability in the whiteboard Jabber protocol in Inkscape allows user-assisted remote attackers to execute arbitrary code via unspecified vectors.
All products containing inkscape were fixed.
- rarpd minor denial of service
A minor denial of service problem was fixed in rarpd, which was sending reply packets with increasing size leading to rarpd not being able to send packets at all anymore and so disabling itself.
This bug has been fixed for all distributions containing rarpd.
- ImageMagick/GraphicsMagick integer overflows
ImageMagick and GraphicsMagick were updated to fix integer overflows in the DCM and XWD code. These bugs could be exploited remotely via other applications.
The problems are tracked by the Mitre CVE IDs CVE-2007-1667 and CVE-2007-1797 and were fixed for all distributions.
- mod_perl denial of service
The mod_perl Apache1 module was affected by insufficient quoting of special characters in the PATH_INFO variable which could lead to excessive resource consumption and a denial of service via a specially crafted URL.
This issue is tracked by the Mitre CVE ID CVE-2007-1349 and was fixed for SUSE Linux Enterprise Server 8 and 9 and dependent products. Newer Enterprise Server versions or SUSE Linux products are not affected, since they only contain the apache2 perl module, which is not affected by the problem.
- dovecot path traversal
A bug in dovecot allowed users to read compressed mailboxes of other users under certain circumstances.
This problem is tracked by the Mitre CVE ID CVE-2007-2231 and was fixed for SUSE Linux 10.1 and openSUSE 10.2. Other products do not contain the dovecot package. ______________________________________________________________________________
2) Pending Vulnerabilities, Solutions, and Work-Arounds
- Month of PHP bugs We are currently working on fixing all the bugs found by the Month of PHP bugs project and will release updates when ready.
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 firstname.lastname@example.org"
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 email@example.com 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:
firstname.lastname@example.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
firstname.lastname@example.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
