Synopsis ========
A buffer overflow in LibAST may result in execution of arbitrary code with escalated privileges.
Background ==========
LibAST is a utility library that was originally intended to accompany Eterm, but may be used by various other applications.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/libast < 0.7 >= 0.7
Description ===========
Michael Jennings discovered an exploitable buffer overflow in the configuration engine of LibAST.
Impact ======
The vulnerability can be exploited to gain escalated privileges if the application using LibAST is setuid/setgid and passes a specifically crafted filename to LibAST's configuration engine.
Workaround ==========
Identify all applications linking against LibAST and verify they are not setuid/setgid.
Resolution ==========
All users should upgrade to the latest version and run revdep-rebuild:
# emerge --sync # emerge --ask --oneshot --verbose >=x11-libs/libast-0.7 # revdep-rebuild
