Synopsis :

Description :

The remote host is affected by the vulnerability described in GLSA-200909-04
(Clam AntiVirus: Multiple vulnerabilities)

Multiple vulnerabilities have been found in ClamAV:
vendor reported a Divide-by-zero error in the PE ('Portable
Windows .exe) file handling of ClamAV
Jeffrey Thomas Peckham found a flaw in
libclamav/untar.c, possibly resulting in an infinite loop when
processing TAR archives in clamd and clamscan (CVE-2009-1270).
Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro
in libclamav/others.h, when processing UPack archives
Nigel disclosed a stack-based buffer overflow
in the 'cli_url_canon()' function in libclamav/phishcheck.c when
processing URLs (CVE-2009-1372).

Impact :

A remote attacker could entice a user or automated system to process a
specially crafted UPack archive or a file containing a specially
crafted URL, possibly resulting in the remote execution of arbitrary
code with the privileges of the user running the application, or a
Denial of Service. Furthermore, a remote attacker could cause a Denial
of Service by supplying a specially crafted TAR archive or PE
executable to a Clam AntiVirus instance.

Workaround :

There is no known workaround at this time.
