Gentoo Linux Security Advisory GLSA 200809-18 - Multiple vulnerabilities in ClamAV may result in a Denial of Service. Hanno boeck reported an error in libclamav/chmunpack.c when processing CHM files (CVE-2008-1389). Other unspecified vulnerabilities were also reported, including a NULL pointer dereference in libclamav (CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913), and file descriptor leaks in libclamav/others.c and libclamav/sis.c (CVE-2008-3914). Versions less than 0.94 are affected.

A vulnerability in ClamAV's chm-parser allowed remote attackers to cause a denial of service (application crash) via a malformed CHM file. A vulnerability in libclamav would allow attackers to cause a denial of service via vectors related to an out-of-memory condition. Multiple memory leaks were found in ClamAV that could possibly allow attackers to cause a denial of service via excessive memory consumption. A number of unspecified vulnerabilities in ClamAV were reported that have an unknown impact and attack vectors related to file descriptor leaks. Other bugs have also been corrected in 0.94 which is being provided with this update. Because this new version has increased the major of the libclamav library, updated dependent packages are also being provided. The previous update had experimental support enabled, which caused ClamAV to report the version as 0.94-exp rather than 0.94, causing ClamAV to produce bogus warnings about the installation being outdated. This update corrects that problem.
