GLSA-200909-04 : Clam AntiVirus: Multiple vulnerabilities

Critical Nessus Plugin ID 40912


The remote Gentoo host is missing one or more security-related patches.


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

Multiple vulnerabilities have been found in ClamAV:
The vendor reported a Divide-by-zero error in the PE ('Portable Executable'; Windows .exe) file handling of ClamAV (CVE-2008-6680).
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 (CVE-2009-1371).
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.


All Clam AntiVirus users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-antivirus/clamav-0.95.2'
