Description Daniel Drake (RETIRED) gentoo-dev 2006-12-21 18:37:49 UTC
The squashfs module of the Linux kernel (2.6.x) fails to properly handle corrupted fs structures, leading to a denial of service and possible data corruption condition. A specially crafted squashfs image will cause the kernel to double free a buffer when a read operation is performed on the corrupted filesystem.

This affects all kernels that include genpatches-extras
