Clam AntiVirus: Multiple vulnerabilities

Clam AntiVirus: Multiple vulnerabilities Clam AntiVirus is subject to vulnerabilities ranging from Denial of Service to execution of arbitrary code when handling compressed executables. clamav 2005-09-19 2005-09-19 106279 remote 0.87 0.87

Clam AntiVirus is a GPL anti-virus toolkit, designed for integration with mail servers to perform attachment scanning. Clam AntiVirus also provides a command line scanner and a tool for fetching updates of the virus database.

Clam AntiVirus is vulnerable to a buffer overflow in "libclamav/upx.c" when processing malformed UPX-packed executables. It can also be sent into an infinite loop in "libclamav/fsg.c" when processing specially-crafted FSG-packed executables.

By sending a specially-crafted file an attacker could execute arbitrary code with the permissions of the user running Clam AntiVirus, or cause a Denial of Service.

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-0.87"
