GLSA-200408-14 : acroread: UUDecode filename buffer overflow

critical Nessus Plugin ID 14570

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200408-14 (acroread: UUDecode filename buffer overflow)

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.

Solution

All acroread users should upgrade to the latest version:
# emerge sync # emerge -pv '>=app-text/acroread-5.09' # emerge '>=app-text/acroread-5.09'
