The function emf_multipart_encrypted() that is used to process encrypted messages is vulnerable to format-string bugs. This bug can be abused by a remote attacker toexecute arbitrary code by sending a crafted encrypted eMail. 2) Solution or Work-Around No work-around. Please install the current security update package. 3) Special Instructions and Notes Please restart evolution. 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 to apply the update, replacing with the filename of the downloaded RPM package. x86 Platform: openSUSE 10.3: 4a13b961952e7913af466ef1738c0196 2ecaf3f223841665df554aa8e20d5978 d06a664885565b04774d5d3c2afb84f5 openSUSE 10.2: c7949a1af35d7abdb7a36fd7fc90607b eadabc26ef71fbb91c498f202196e640 b8a8b80039aa8f1641c0103bb04f75a0 SUSE LINUX 10.1: cc40ee93e3f2043a25dff22e62bc4e4e b7fb5fec304a0e623be28233a66525ad d2833e3948641af99a9e76026da6e8da Power PC Platform: openSUSE 10.3: a6e9d56b825c7809bc62a87f546bdb50 772ce1adbb46a5ba5f703bf4dcfbd49e 946a9756bab858d4242736e055009173 openSUSE 10.2: fa5ed56ee0d3a6718015bf722e34ff6f 91565615e83f40a40d435e9edcca2a63 443a51070cdb147473536fec3b704533 SUSE LINUX 10.1: 8b0beec2e2ecad7969fc91aa12c963d2 46706e204d46f01026af35b861c101a6 0c946a3533d2a55812f0fd60886e097f x86-64 Platform: openSUSE 10.3: 6c9f98241bf08edc4a77d52c4232ed60 bab5d0660dbb9076bd865ccae25bc68d 44778c1ea873e4e54021ce3588f406de openSUSE 10.2: 8ac28a5b6875266d281400060867b45f 970d89a3ae7574334586a6b9388e1073 6ffb4564be38436e91a0b10b908ff18d SUSE LINUX 10.1: c352e53bfd35cb08ef87102829ed2dcb a4d5259610db7850b39e2b4ae2b7a00e 50dae7030db765effccf36e23f112671 Sources: openSUSE 10.3: 483dffff6981e43065de58916fc7faa0 openSUSE 10.2: ba7d8312622f37c7d05dba4e6d03a5e0 SUSE LINUX 10.1: 93827395e2d05427ea717d882f444da5 Our maintenance customers are notified individually.

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 replacing with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team " where is replaced by the date the document was signed. If thesecurity 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 to verify the signature of the package, replacing with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from This email address is being protected from spambots. You need JavaScript enabled to view it. 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 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 This email address is being protected from spambots. You need JavaScript enabled to view it.), the checksums show proof of the authenticity of the package if the signature of theannouncement 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: This email address is being protected from spambots.
