USN102-1 : sharutils vulnerabilities

Vulnerability Assessment Summary
sharutils vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- sharutils
- sharutils-doc


Description :

Shaun Colley discovered a buffer overflow in "shar" that was triggered
by output files (specified with -o) with names longer than 49
characters. This could be exploited to run arbitrary attacker
specified code on systems that automatically process uploaded files
with shar.

Ulf Harnhammar discovered that shar does not check the data length
returned by the 'wc' command. However, it is believed that this cannot
actually be exploited on real systems.

Solution :

Upgrade to :
- sharutils-4.2.1-10ubuntu0.1 (Ubuntu 4.10)
- sharutils-doc-4.2.1-10ubuntu0.1 (Ubuntu 4.10)
