Description

An information disclosure vulnerability was discovered in Bouncy Castle, a Java library which consists of various cryptographic algorithms. The Galois/Counter mode (GCM) implementation was missing a boundary check that could enable a local application to gain access to user's private information.

For Debian 7 'Wheezy', these problems have been fixed in version 1.44+dfsg-3.1+deb7u2.

We recommend that you upgrade your bouncycastle packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
