Description of problem:
Remote exploitation of an integer overflow vulnerability in Clam AntiVirus' 
ClamAV, as included in various vendors' operating system distributions, allows 
attackers to execute arbitrary code with the privileges of the affected 
process. 

The vulnerability exists within the code responsible for parsing and scanning 
PE files. While iterating through all sections contained in the PE file, 
several attacker controlled values are extracted from the file. On each 
iteration, arithmetic operations are performed without taking into 
consideration 32-bit integer wrap. 

Since insufficient integer overflow checks are present, an attacker can cause
a heap overflow by causing a specially crafted Petite packed PE binary to be 
scanned. This results in an exploitable memory corruption condition.

Version-Release number of selected component (if applicable):
clamav-0.92-4.1

Expected results:
Immediate upgrade to 0.92.1
