Detail

Synopsis

A NULL pointer dereference in Cyrus-SASL may allow remote attackers to cause a Denial of Service condition.

Background

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

Description

In the GNU C Library (glibc) from version 2.17 onwards, the crypt()
function call can return NULL when the salt violates specifications or the system is in FIPS-140 mode and a DES or MD5 hashed password is passed. When Cyrus-SASL's authentication mechanisms call crypt(), a NULL may be returned.

Impact

A remote attacker could trigger this vulnerability to cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Cyrus-SASL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/cyrus-sasl-2.1.26-r3"
