High

Base vector

AV:L/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions FreeBSD versions 7.1 through 8.1-PRERELEASE

Description The issue allows local users to cause a denial of service, resulting in system file corruption, and potentially gain privileges. This is achieved via the sendfile system call, which does not properly copy the read-only flag when creating a duplicate mbuf buffer reference.

Recommendations For FreeBSD versions 7.1 through 8.1-PRERELEASE, consider restricting access to the sendfile system call until a patch is available to prevent potential exploitation.
