"It was discovered that there was an information leak vulnerability in
openafs, a distributed filesystem.

Due to incomplete initialization or clearing of reused memory, OpenAFS
directory objects are likely to contain 'dead' directory entry
information.

For Debian 7 'Wheezy', this issue has been fixed in openafs version
1.6.1-3+deb7u7.

We recommend that you upgrade your openafs 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.");
