[GLSA]

Gentoo Linux Security Advisory

Title: ClamAV: Multiple vulnerabilities (GLSA 200805-19)
Severity: high
Exploitable: remote
Date: May 20, 2008
Bug(s): #213762
ID: 200805-19

Synopsis

Multiple vulnerabilities in ClamAV may result in the remote execution of arbitrary code.

Background

Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.

Affected Packages

Package: app-antivirus/clamav
Vulnerable: < 0.93
Unaffected: >= 0.93
Architectures: All supported architectures


Description

Multiple vulnerabilities have been reported:

• Damian Put reported a heap-based buffer overflow when processing PeSpin packed PE binaries (CVE-2008-0314).
• Alin Rad Pop of Secunia Research reported a buffer overflow in the cli_scanpe() function when processing Upack PE binaries (CVE-2008-1100).
• Hanno Boeck reported an infinite loop when processing ARJ archives (CVE-2008-1387).
• Damian Put and Thomas Pollet reported a heap-based buffer overflow when processing WWPack compressed PE binaries (CVE-2008-1833).
• A buffer over-read was discovered in the rfc2231() function when producing a string that is not NULL terminated (CVE-2008-1836).
• An unspecified vulnerability leading to "memory problems" when scanning RAR files was reported (CVE-2008-1837).
• Thierry Zoller reported that scanning of RAR files could be circumvented (CVE-2008-1835).

Impact

A remote attacker could entice a user or automated system to scan a specially crafted file, possibly leading to the execution of arbitrary code with the privileges of the user running ClamAV (either a system user or the "clamav" user if clamd is compromised), or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All ClamAV users should upgrade to the latest version:
