Background ========= Sylpheed is a lightweight email client and newsreader. Sylpheed-Claws is a 'bleeding edge' version of Sylpheed. They both support the import of address books in LDIF (Lightweight Directory Interchange Format). Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/sylpheed < 2.0.4 > = 2.0.4 2 mail-client/sylpheed-claws < 1.0.5-r1 > = 1.0.5-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description ========== Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store data of variable length. Two similar problems exist also in the Mutt and Pine addressbook importers of Sylpheed-Claws. Impact ===== By convincing a user to import a specially-crafted LDIFfile into the address book, a remote attacker could cause the program to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the software. Workaround ========= There is no known workaround at this time. Resolution ========= All Sylpheed users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =mail-client/sylpheed-2.0.4" All Sylpheed-Claws users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =mail-client/sylpheed-claws-1.0.5-r1" References ========= [ 1 ] CVE-2005-3354 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200511-13 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
