GLSA-200711-33 : nss_ldap: Information disclosure
Medium Nessus Plugin ID 28322
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200711-33 (nss_ldap: Information disclosure)
Josh Burley reported that nss_ldap does not properly handle the LDAP connections due to a race condition that can be triggered by multi-threaded applications using nss_ldap, which might lead to requested data being returned to a wrong process.
Remote attackers could exploit this race condition by sending queries to a vulnerable server using nss_ldap, possibly leading to theft of user credentials or information disclosure (e.g. Dovecot returning wrong mailbox contents).
There is no known workaround at this time.
SolutionAll nss_ldap users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-auth/nss_ldap-258'
