CVE-2002-1571 kernel leaks register information to other processes
Last modified: 2007-11-30 17:06:51 EST
The AS kernel leaks the contents of the XMM registers (Screaming Sindy) to other
processes as it fails to zero them on process start and during ptrace. Since
those registers are mostly used by crypto programs this security leak can be
rather senstive. Patch available for 2.4.18; will apply to 2.4.9 with minimal
Fixed in AS2.1 errata kernel-2.4.9-e.8, released on 7/29.
