medium Nessus Plugin ID 69538

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The 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.
 Impact :

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

 There is no known workaround at this time.

Solution

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