GENTOO LINUX SECURITY ANNOUNCEMENT 200210-012
- - --------------------------------------------------------------------

PACKAGE : sharutils
SUMMARY : inadequate checks on user-specified output files
DATE    : 2002-10-30 14:10 UTC
EXPLOIT : local

- - --------------------------------------------------------------------

The uudecode utility would create an output file without checking
to see if it was about to write to a symlink or a pipe. If a
user uses uudecode to extract data into open shared directories,
such as /tmp, this vulnerability could be used by a local attacker
to overwrite files or lead to privilege escalation.

SOLUTION

It is recommended that all Gentoo Linux users who are running
sys-apps/sharutils-4.2.1-r5 and earlier update their systems as follows:

emerge rsync
emerge sharutils
emerge clean
