CVE-2006-0145

The kernfsxread function in kernfs in NetBSD 1.6 through 2.1, and OpenBSD 3.8, does not properly validate file offsets against negative 32-bit values that occur as a result of truncation, which allows local users to read arbitrary kernel memory and gain privileges via the lseek system call...

CVE-2005-4351

CVE-2005-4351 – Summary (concrete details from connected docs): The vulnerability affects BSD Securelevels implementations in FreeBSD (up to 6.0-STABLE and 7.0-CURRENT), OpenBSD (up to 3.8), DragonFly (up to 1.2), and Linux (up to 2.6.15). The root cause is that, while securelevels protect files ...
