Synopsis ========
A vulnerability potentially allowing remote execution of arbitrary code has been discovered in the neon library.
Background ==========
neon provides an HTTP and WebDAV client library.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/neon <= 0.24.5 >= 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"
