Detail

Multiple vulnerabilities has been found and corrected in clamav:

Unspecified vulnerability in ClamAV before 0.95 allows remote attackers to bypass detection of malware via a modified RAR archive (CVE-2009-1241).

libclamav/pe.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (crash) via a crafted EXE file that triggers a divide-by-zero error (CVE-2008-6680).

libclamav/untar.c in ClamAV before 0.95 allows remote attackers to cause a denial of service (infinite loop) via a crafted file that causes (1) clamd and (2) clamscan to hang (CVE-2009-1270).

The CLI_ISCONTAINED macro in libclamav/others.h in ClamAV before 0.95.1 allows remote attackers to cause a denial of service (application crash) via a malformed file with UPack encoding (CVE-2009-1371).

Stack-based buffer overflow in the cli_url_canon function in libclamav/phishcheck.c in ClamAV before 0.95.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted URL (CVE-2009-1372).

Important notice about this upgrade: clamav-0.95+ bundles support for RAR v3 in libclamav which is a license violation as the RAR v3 license and the GPL license is not compatible. As a consequence to this Mandriva has been forced to remove the RAR v3 code.

This update provides clamav 0.95.1, which is not vulnerable to these issues.
