vulnerability CVE-2012-3466

GNOME Keyring: non expiration of gpg cache

Synthesis of the vulnerability

Authentication data stored in the GNOME Keyring gpg cache do not expire after the idle time defined by the administrator.
Impacted products: Fedora, MBS, openSUSE, Unix (platform).
Severity: 1/4.
Creation date: 09/08/2012.
Identifiers: 681081, 845426, BID-54920, CVE-2012-3466, FEDORA-2012-12368, MDVSA-2013:084, openSUSE-SU-2012:1121-1, VIGILANCE-VUL-11835.

Description of the vulnerability

The GNOME Keyring tool stores user's passwords (session, ssh, gpg, etc.), so they are not requested again.

The org.gnome.crypto.cache gpg-cache-ttl option (in mode "idle") defines the expiration delay for stored data. However, the daemon/gpg-agent/gkd-gpg-agent-ops.c file, which implements the gpg cache, does not use this option.

Authentication data stored in the GNOME Keyring gpg cache therefore do not expire after the idle time defined by the administrator.
