**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.18.2 **Description** The issue is related to an off-by-one error in the `ecryptfs decode from filename` function in the eCryptfs subsystem. This error can be exploited by local users to cause a denial of service, resulting in a buffer overflow and system crash, or possibly gain privileges via a crafted filename. There is also mention of multiple vulnerabilities in the linux-image-3.2.0 package of the Ubuntu operating system that can lead to violations of confidentiality, integrity, and availability of protected information, potentially exploitable remotely. **Recommendations** For Linux kernel versions prior to 3.18.2, update to version 3.18.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the `ecryptfs decode from filename` function until a patch is available. Avoid using crafted filenames that could exploit the off-by-one error in the `ecryptfs decode from filename` function until the issue is resolved.
