Background ========== GNU Arch (tla) is a revision control system suited for widely distributed development. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/tla < 1.2.1_pre1 >= 1.2.1_pre1 Description =========== Stefan Esser discovered a vulnerability in the code of the neon library (GLSA 200405-13): if a malicious date string is passed to the ne_rfc1036_parse() function, it can trigger a string overflow into static heap variables. tla includes it's own version of the library. Impact ====== When connected to a malicious WebDAV server, this vulnerability could allow execution of arbitrary code with the rights of the user running tla. Workaround ========== There is no known workaround at this time. Resolution ========== All users of tla should upgrade to the latest stable version: # emerge sync # emerge -pv ">=dev-util/tla-1.2.1_pre1" # emerge ">=dev-util/tla-1.2.1_pre1" References ========== [ 1 ] GLSA 200405-13 http://www.gentoo.org/security/en/glsa/glsa-200405-13.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200405-25.xml 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.
