USN116-1 : gzip vulnerabilities

Vulnerability Assessment Summary
gzip vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote package "gzip" is missing a security patch.

Description :

Imran Ghory discovered a race condition in the file permission restore
code of gzip and gunzip. While a user was compressing or decompressing
a file, a local attacker with write permissions in the directory of
that file could replace the target file with a hard link. This would
cause gzip to restore the file permissions to the hard link target
instead of to the gzip output file, which could be exploited to gain
read or even write access to files of other users. (CVE-2005-0988)

Ulf Harnhammar found a path traversal vulnerability when gunzip was
used with the -N option. A possible hacker could exploit this to create
files in an arbitrary directory with the permissions of a user if he
tricked this user to decompress a specially crafted gzip file using
the -N option (which can also happen in systems that automatically
process uploaded gzip files). (CVE-2005-1228)

Solution :

Upgrade to :
- gzip-1.3.5-9ubuntu3.2 (Ubuntu 4.10)
- gzip-1.3.5-9ubuntu3.2 (Ubuntu 5.04)
