    Debian: clamav fix denial of service DSA-1616-2

    Date 25 Jul 2008
    2511
    Posted By LinuxSecurity Advisories
    Damian Put discovered a vulnerability in the ClamAV anti-virus toolkit's parsing of Petite-packed Win32 executables. The weakness leads to an invalid memory access, and could enable an attacker to crash clamav by supplying a maliciously crafted Petite-compressed binary for scanning. In some configurations, such as when clamav is used in combination with mail servers, this could cause a system to "fail open," facilitating a follow-on viral attack.

    This update corrects a packaging and build error in the packages
    released in DSA-1616-1.  Those packages, while functional, did not
    actually apply the fix intended.  This update restores the fix
    to the package build; no other changes are introduced.  For
    reference, the text of the original advisory follows.
    
    Damian Put discovered a vulnerability in the ClamAV anti-virus
    toolkit's parsing of Petite-packed Win32 executables.  The weakness
    leads to an invalid memory access, and could enable an attacker to
    crash clamav by supplying a maliciously crafted Petite-compressed
    binary for scanning.  In some configurations, such as when clamav
    is used in combination with mail servers, this could cause a system
    to "fail open," facilitating a follow-on viral attack.
    
    The Common Vulnerabilities and Exposures project identifies this
    weakness as CVE-2008-2713.
    
    For the stable distribution (etch), this problem has been fixed in
    version 0.90.1dfsg-3.1+etch14.  For the unstable distribution (sid),
    the problem has been fixed in version 0.93.1.dfsg-1.1.
    
    We recommend that you upgrade your clamav packages.
