Title: Cyrus-SASL: Denial of Service (GLSA 201309-01)
Date: September 01, 2013
A NULL pointer dereference in Cyrus-SASL may allow remote attackers
to cause a Denial of Service condition.
Cyrus-SASL is an implementation of the Simple Authentication and
Vulnerable: < 2.1.26-r3
Unaffected: >= 2.1.26-r3
Architectures: All supported architectures
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.
A remote attacker could trigger this vulnerability to cause a Denial of
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-2.1.26-r3"
