CVE-2008-4554 is a vulnerability of currently unknown severity. The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 does not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
Description
