NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
