USN-385-1: tar vulnerability

tar vulnerability
Releases
Details
Teemu Salmela discovered that tar still handled the deprecated
GNUTYPE_NAMES record type. This record type could be used to create
symlinks that would be followed while unpacking a tar archive. If a
user or an automated system were tricked into unpacking a specially
crafted tar file, arbitrary files could be overwritten with user
privileges.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 6.10
-
tar
-
1.15.91-2ubuntu0.3
Ubuntu 6.06
-
tar
-
1.15.1-2ubuntu2.1
Ubuntu 5.10
-
tar
-
1.15.1-2ubuntu0.2
In general, a standard system upgrade is sufficient to effect the
necessary changes.
