ClamAV: Multiple vulnerabilities

ClamAV: Multiple vulnerabilities Multiple vulnerabilities have been discovered in ClamAV allowing for the remote execution of arbitrary code. ClamAV 2007-04-24 2007-04-24 174375 remote 0.90.2 0.90.2

ClamAV is a GPL virus scanner.

iDefense Labs have reported a stack-based buffer overflow in the cab_unstore() function when processing negative values in .cab files. Multiple file descriptor leaks have also been reported in chmunpack.c, pdf.c and dblock.c when processing .chm files.

A remote attacker could send a specially crafted CHM file to the scanner, possibly resulting in the remote execution of arbitrary code with the privileges of the user running ClamAV.

There is no known workaround at this time.

All ClamAV users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.90.2"
