7.2 · HIGHOverview
CVE-2004-0077 is a high-severity vulnerability affecting redhat bigmem_kernel. It was published on March 3, 2004 and has a CVSS 2.0 base score of 7.2 (HIGH).
This vulnerability has a CVSS 2.0 base score of 7.2, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The do_mremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the do_munmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different vulnerability than CAN-2003-0985.
Remediation
Check the references section for vendor advisories and patches from redhat. Update bigmem_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
