Synopsis
Multiple vulnerabilities have been found in Linux-PAM, allowing local attackers to possibly gain escalated privileges, cause a Denial of Service, corrupt data, or obtain sensitive information.
Background
Linux-PAM (Pluggable Authentication Modules) is an architecture allowing the separation of the development of privilege granting software from the development of secure and appropriate authentication schemes.
Affected Packages
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-libs/pam < 1.1.5 >= 1.1.5
Impact
===== A local attacker could use specially crafted files to cause a buffer overflow, possibly resulting in privilege escalation or Denial of Service. Furthermore, a local attacker could execute specially crafted programs or symlink attacks, possibly resulting in data loss or disclosure of sensitive information.
Workaround
There is no known workaround at this time.
