CVE-2009-2406: Buffer Overflow

Q: What is the severity of CVE-2009-2406?

CVE-2009-2406 is classified as a high severity vulnerability due to its capability to cause a denial of service or escalate privileges.

Q: How do I fix CVE-2009-2406?

To fix CVE-2009-2406, update your Linux kernel to version 2.6.30.4 or later.

Q: What are the consequences of the vulnerability CVE-2009-2406?

The consequences include potential system crashes or unauthorized privilege escalation via crafted eCryptfs files.

Q: Which Linux kernel versions are affected by CVE-2009-2406?

CVE-2009-2406 affects Linux kernel versions prior to 2.6.30.4, including several 2.6.x and earlier versions.

Q: Who is impacted by CVE-2009-2406?

Local users on systems running vulnerable versions of the Linux kernel may be impacted by CVE-2009-2406.

Published Jul 31, 2009

Updated

Stack-based buffer overflow in the parsetag11packet 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.
