Synopsis ========
acroread contains two errors in the handling of UUEncoded filenames that may lead to execution of arbitrary code or programs.
Background ==========
acroread is Adobe's Acrobat PDF reader for Linux.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/acroread <= 5.08 >= 5.09
Description ===========
acroread contains two errors in the handling of UUEncoded filenames. First, it fails to check the length of a filename before copying it into a fixed size buffer and, secondly, it fails to check for the backtick shell metacharacter in the filename before executing a command with a shell.
Impact ======
By enticing a user to open a PDF with a specially crafted filename, an attacker could execute arbitrary code or programs with the permissions of the user running acroread.
Workaround ==========
There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of acroread.
Resolution ==========
All acroread users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=app-text/acroread-5.09" # emerge ">=app-text/acroread-5.09"
