gzip - several

Two problems have been discovered in gzip, the GNU compression
utility. The Common Vulnerabilities and Exposures project identifies
the following problems.

• CAN-2005-0988
  Imran Ghory discovered a race condition in the permissions setting
  code in gzip. When decompressing a file in a directory an
  attacker has access to, gunzip could be tricked to set the file
  permissions to a different file the user has permissions to.

• CAN-2005-1228
  Ulf Härnhammar discovered a path traversal vulnerability in
  gunzip. When gunzip is used with the -N option an attacker could
  use
  this vulnerability to create files in an arbitrary directory with
  the permissions of the user.

For the oldstable distribution (woody) these problems have been fixed in
version 1.3.2-3woody5.

For the stable distribution (sarge) these problems have been fixed in
version 1.3.5-10.

For the unstable distribution (sid) these problems have been fixed in
version 1.3.5-10.

We recommend that you upgrade your gzip package.
