openafs

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2015-8312, CVE-2016-2860, CVE-2016-4536.

More information:

• CVE-2015-8312

  Off-by-one error in afs_pioctl.c in OpenAFS before 1.6.16 might allow local users to cause a denial of service (memory overwrite and system crash) via a pioctl with an input buffer size of 4096 bytes.

• CVE-2016-2860

  The newEntry function in ptserver/ptprocs.c in OpenAFS before 1.6.17 allows remote authenticated users from foreign Kerberos realms to bypass intended access restrictions and create arbitrary groups as administrators by leveraging mishandling of the creator ID.

• CVE-2016-4536

  The client in OpenAFS before 1.6.17 does not properly initialize the (1) AFSStoreStatus, (2) AFSStoreVolumeStatus, (3) VldbListByAttributes, and (4) ListAddrByAttributes structures, which might allow remote attackers to obtain sensitive memory information by leveraging access to RPC call traffic.

For Debian 7 Wheezy, these problems have been fixed in version 1.6.1-3+deb7u6.

We recommend that you upgrade your openafs packages.
