CVE-2010-4650

Publication date 12 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Buffer overflow in the fuse_do_ioctl function in fs/fuse/file.c in the Linux kernel before 2.6.37 allows local users to cause a denial of service or possibly have unspecified other impact by leveraging the ability to operate a CUSE server.

From the Ubuntu Security Team

An error was discovered in the kernel's handling of CUSE (Character device in Userspace). A local attacker might exploit this flaw to escalate privilege, if access to /dev/cuse has been modified to allow non-root users.
