CVE-2006-6304
Description
From CVE.org
The do_coredump function in fs/exec.c in the Linux kernel 2.6.19 sets the flag variable to O_EXCL but does not use it, which allows context-dependent attackers to modify arbitrary files via a rewrite attack during a core dump.

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).
