SB2013030503 - Buffer overflow in arthurdejong nss-pam-ldapd

Description

This security bulletin contains information about 1 vulnerability.

1) Buffer overflow (CVE-ID: CVE-2013-0288)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

nss-pam-ldapd before 0.7.18 and 0.8.x before 0.8.11 allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code by performing a name lookup on an application with a large number of open file descriptors, which triggers a stack-based buffer overflow related to incorrect use of the FD_SET macro.

Remediation

Install update from vendor's website.
