|Gentoo Linux Security Advisory
Title: acroread: UUDecode filename buffer overflow (GLSA 200408-14)
Date: August 15, 2004
Updated: May 22, 2006
acroread contains two errors in the handling of UUEncoded filenames that
may lead to execution of arbitrary code or programs.
acroread is Adobe's Acrobat PDF reader for Linux.
Vulnerable: <= 5.08
Unaffected: >= 5.09
Architectures: All supported architectures
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.
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.
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of acroread.
All acroread users should upgrade to the latest version:
|# emerge sync
# emerge -pv ">=app-text/acroread-5.09"
# emerge ">=app-text/acroread-5.09"
