CVE-2009-2406 Detail

Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

Description

Stack-based buffer overflow in the parse_tag_11_packet function in fs/ecryptfs/keystore.c in the eCryptfs subsystem in the Linux kernel before 2.6.30.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving a crafted eCryptfs file, related to not ensuring that the key signature length in a Tag 11 packet is compatible with the key signature buffer size.

Vendor Statements (disclaimer)

Official Statement from Red Hat (08/18/2009)

The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, and Red Hat Enterprise MRG did not include support for eCryptfs, and therefore are not affected by this issue. Red Hat Enterprise Linux 5 was vulnerable to this issue and was addressed via: https://rhn.redhat.com/errata/RHSA-2009-1193.html
