Synopsis ========
A vulnerability in LinuxCIFS utils' "cifscreds" PAM module might allow remote attackers to have an unspecified impact via unknown vectors.
Background ==========
The LinuxCIFS utils are a collection of tools for managing Linux CIFS Client Filesystems.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/cifs-utils < 6.4 >= 6.4
Description ===========
A stack-based buffer overflow was discovered in cifskey.c or cifscreds.c in LinuxCIFS, as used in "pam_cifscreds."
Impact ======
A remote attacker could exploit this vulnerability to cause an unspecified impact.
Workaround ==========
Don't use LinuxCIFS utils' "cifscreds" PAM module. In Gentoo, LinuxCIFS utils' PAM support is disabled by default unless the "pam" USE flag is enabled.
Resolution ==========
All LinuxCIFS utils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/cifs-utils-6.4"
References ==========
