CVE-2014-9683
Published: 31 December 2014
Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel before 3.18.2 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename.
From the Ubuntu Security Team
Dmitry Chernenkov discovered a buffer overflow in eCryptfs' encrypted file name decoding. A local unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges.
