Gentoo Linux Security Advisory

Title: Cyrus-SASL: Buffer overflow and SASL_PATH vulnerabilities (GLSA 200410-05)
Severity: high
Exploitable: remote
Date: October 07, 2004
Updated: May 22, 2006
Bug(s): #56016
ID: 200410-05

Synopsis

Cyrus-SASL contains two vulnerabilities that might allow an attacker to completely compromise the vulnerable system.

Background

Cyrus-SASL is an implementation of the Simple Authentication and Security Layer.

Affected Packages

Package: dev-libs/cyrus-sasl
Vulnerable: <= 2.1.18-r1
Unaffected: >= 2.1.18-r2
Architectures: All supported architectures


Description

Cyrus-SASL contains a remote buffer overflow in the digestmda5.c file. Additionally, under certain conditions it is possible for a local user to exploit a vulnerability in the way the SASL_PATH environment variable is honored (CAN-2004-0884).

Impact

An attacker might be able to execute arbitrary code with the Effective ID of the application calling the Cyrus-SASL libraries.

Workaround

There is no known workaround at this time.

Resolution

All Cyrus-SASL users should upgrade to the latest stable version:
Code:
# emerge sync
# emerge -pv ">=dev-libs/cyrus-sasl-2.1.18-r2"
# emerge ">=dev-libs/cyrus-sasl-2.1.18-r2"


References
