Amazon Linux 1 Security Advisory: ALAS-2013-237
Advisory Release Date: 2013-10-23 15:24 Pacific
Advisory Updated Date: 2014-09-16 21:46 Pacific
GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey.
The compressed packet parser in GnuPG 1.4.x before 1.4.15 and 2.0.x before 2.0.22 allows remote attackers to cause a denial of service (infinite recursion) via a crafted OpenPGP message.
Affected Packages:
gnupg2
Issue Correction:
Run yum update gnupg2 to update your system.
