DoS, System access

WHERE:
>From remote

SOFTWARE:
Clam AntiVirus (clamav) 0.x
http://secunia.com/product/2538/

DESCRIPTION:
Some vulnerabilities have been reported in ClamAV, which potentially
can be exploited by malicious people to cause a DoS (Denial of
Service) and compromise a vulnerable system.

1) An unspecified integer overflow error exists in the PE header
parser in "libclamav/pe.c".

Successful exploitation requires that the ArchiveMaxFileSize option
is disabled.

2) Some format string errors in the logging handling in
"shared/output.c" may be exploited to execute arbitrary code.

3) An out-of-bounds memory access error in the "cli_bitset_test()"
function in "ibclamav/others.c" may be exploited to cause a crash.

The vulnerabilities have been reported in version 0.88. Prior
versions may also be affected.

SOLUTION:
Update to version 0.88.1.
http://sourceforge.net/project/showfiles.php?group_id=86638&release_id=407078
