Debian DLA-342-1 : openafs security update

Medium Nessus Plugin ID 86920

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been found and solved in the distributed file system OpenAFS :

CVE-2015-3282

vos leaked stack data clear on the wire when updating vldb entries.

CVE-2015-3283

OpenAFS allowed remote attackers to spoof bos commands via unspecified vectors.

CVE-2015-3285

pioctl wrongly used the pointer related to the RPC, allowing local users to cause a denial of service (memory corruption and kernel panic) via a crafted OSD FS command.

CVE-2015-6587

vlserver allowed remote authenticated users to cause a denial of service (out-of-bounds read and crash) via a crafted regular expression in a VL_ListAttributesN2 RPC.

CVE-2015-7762 and CVE-2015-7763 ('Tattletale')

John Stumpo found that Rx ACK packets leaked plaintext of packets previously processed.

For Debian 6 'Squeeze', these problems have been fixed in openafs version 1.4.12.1+dfsg-4+squeeze4.

We recommend that you upgrade your OpenAFS packages.
