Mandriva Linux Security Advisory : nss-pam-ldapd (MDVSA-2013:106)
Medium Nessus Plugin ID 66118
SynopsisThe remote Mandriva Linux host is missing a security update.
DescriptionUpdated nss-pam-ldapd packages fixes the following security vulnerability :
Garth Mollett discovered that a file descriptor overflow issue in the use of FD_SET() in nss-pam-ldapd can lead to a stack-based buffer overflow. An attacker could, under some circumstances, use this flaw to cause a process that has the NSS or PAM module loaded to crash or potentially execute arbitrary code.
The issue can be triggered in a network daemon by opening a large number of connections and forcing a name lookup. This would result in a crash and possibly remote code execution. This issue may also allow local privilege escalation if a suid program does name lookups and doesn't close file descriptors inherited from the parent process (CVE-2013-0288).
SolutionUpdate the affected nss-pam-ldapd package.
