|Gentoo Linux Security Advisory
Title: Cyrus-SASL: DIGEST-MD5 Pre-Authentication Denial of Service (GLSA 200604-09)
Date: April 21, 2006
Cyrus-SASL contains a vulnerability in the DIGEST-MD5 process that could lead to a Denial of Service.
Cyrus-SASL is an implementation of the Simple Authentication and Security Layer.
Vulnerable: < 2.1.21-r2
Unaffected: >= 2.1.21-r2
Architectures: All supported architectures
Cyrus-SASL contains an unspecified vulnerability in the DIGEST-MD5 process that could lead to a Denial of Service.
An attacker could possibly exploit this vulnerability by sending specially crafted data stream to the Cyrus-SASL server, resulting in a Denial of Service even if the attacker is not able to authenticate.
There is no known workaround at this time.
All Cyrus-SASL users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/cyrus-sasl-2.1.21-r2"
