Background ========= neon provides an HTTP and WebDAV client library. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/neon = 0.24.6 Description ========== Stefan Esser discovered a vulnerability in the code of the neon library : if a malicious date string is passed to the ne_rfc1036_parse() function, it can trigger a string overflow into static heap variables. Impact ===== Depending on the application linked against libneon and when connected to a malicious WebDAV server, this vulnerability could allow execution of arbitrary code with the rights of the user running that application. Workaround ========= There is no known workaround at this time. All users are advised to upgrade to the latest available version of neon. Resolution ========= All users of neon should upgrade to the latest stable version: # emerge sync # emerge -pv "> =net-misc/neon-0.24.6" # emerge "> =net-misc/neon-0.24.6" References ========= [ 1 ]E-matters advisory 06/2004 [ 2 ] CAN-2004-0398 https://www.cve.org/CVERecord?id=CAN-2004-0398 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200405-13 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.
