Name of the Vulnerable Software and Affected Versions ecryptfs-utils versions prior to 90

Description The issue concerns multiple vulnerabilities in the ecryptfs-utils package, which can lead to disruption of confidentiality, integrity, and availability of protected information. These vulnerabilities can be exploited locally, allowing attackers to cause a denial of service or bypass unmounting restrictions. The utils/mount.ecryptfs private.c file in ecryptfs-utils does not properly maintain the mtab file during error conditions, enabling local users to corrupt tables or bypass intended unmounting restrictions via a umount system call.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
