GLSA-201309-01 : Cyrus-SASL: Denial of Service
Medium Nessus Plugin ID 69538
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201309-01 (Cyrus-SASL: Denial of Service)
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 Service condition.
There is no known workaround at this time.
SolutionAll Cyrus-SASL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/cyrus-sasl-2.1.26-r3'
