Detail
Problem Description: Updated nss-pam-ldapd packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: The nss-pam-ldapd packages provide the nss-pam-ldapd daemon (nslcd), which uses a directory server to lookup name service information on behalf of a lightweight nsswitch module. An array index error, leading to a stack-based buffer overflow flaw, was found in the way nss-pam-ldapd managed open file descriptors. An attacker able to make a process have a large number of open file descriptors and perform name lookups could use this flaw to cause the process to crash or, potentially, execute arbitrary code with the privileges of the user running the process. (CVE-2013-0288) Red Hat would like to thank Garth Mollett for reporting this issue. All users of nss-pam-ldapd are advised to upgrade to these updated packages, which contain a backported patch to fix this issue. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 909119 - CVE-2013-0288 nss-pam-ldapd: FD_SET array index error, leading to stack-based buffer overflow |

Title: | DSA-2628-1 nss-pam-ldapd - buffer overflow | ||
Description: | Garth Mollett discovered that a file descriptor overflow issue in the use of FD_SET() in nss-pam-ldapd, which provides NSS and PAM modules for using LDAP as a naming service, 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. | ||

Description: | 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. | ||
