GLSA 200604-06: ClamAV: Multiple vulnerabilities

Severity:high
Title:ClamAV: Multiple vulnerabilities
Date:04/07/2006
Bugs: #128963
ID:200604-06

Synopsis

ClamAV contains multiple vulnerabilities that could lead to remote execution of arbitrary code or cause an application crash.

Background

ClamAV is a GPL virus scanner.

Affected packages

Package Vulnerable Unaffected Architecture(s)
app-antivirus/clamav < 0.88.1 >= 0.88.1 All supported architectures

Description

ClamAV contains format string vulnerabilities in the logging code (CVE-2006-1615). Furthermore Damian Put discovered an integer overflow in ClamAV's PE header parser (CVE-2006-1614) and David Luyer discovered that ClamAV can be tricked into performing an invalid memory access (CVE-2006-1630).

Impact

By sending a malicious attachment to a mail server running ClamAV, a remote attacker could cause a Denial of Service or the execution of arbitrary code. Note that the overflow in the PE header parser is only exploitable when the ArchiveMaxFileSize option is disabled.

Workaround

There is no known workaround at this time.

Resolution

All ClamAV users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.88.1"
