Package        : cabextract
Vulnerability  : missing directory sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0916
Debian Bug     : 277522

The upstream developers discovered a problem in cabextract, a tool to
extract cabinet files.  The program was able to overwrite files in
upper directories.  This could lead an attacker to overwrite arbitrary
files.

For the stable distribution (woody) this problem has been fixed in
version 0.2-2b.

For the unstable distribution (sid) this problem has been fixed in
version 1.1-1.

We recommend that you upgrade your cabextract package.
