Amazon Linux AMI : gnupg (ALAS-2014-278)

low Nessus Plugin ID 72296

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption.
NOTE: applications are not typically expected to protect themselves from acoustic side-channel attacks, since this is arguably the responsibility of the physical device. Accordingly, issues of this type would not normally receive a CVE identifier. However, for this issue, the developer has specified a security policy in which GnuPG should offer side-channel resistance, and developer-specified security-policy violations are within the scope of CVE.

Solution

Run 'yum update gnupg' to update your system.
