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 https://security.gentoo.org/glsa/200405-13 Availability =========== This GLSA andany updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200405-25 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.
