Debian DLA-493-1 : openafs security update
high Nessus Plugin ID 91360
Language:
Synopsis
The remote Debian host is missing a security update.Description
- 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.
