CVE-2010-4650
Description
From CVE.org
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.
Statement
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the upstream commit 59efec7b that introduced this issue. It did not affect the version of Linux kernel as shipped with Red hat Enterprise MRG as it did not provide support for Character device in Userspace (CUSE). A future kernel update in Red Hat Enterprise Linux 6 may address this flaw. Note that, by default, the "/dev/cuse" file in Red Hat Enterprise Linux 6 is only accessible by the root user.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
