CVE-2017-6949

CVE-2017-6949 affects CHICKEN Scheme up to version 4.12.0. A nonstandard CHICKEN extension allocates an SRFI-4 vector in unmanaged memory, and the vector size is passed to malloc() without sanitisation. An unexpected size can lead to a segfault or a buffer overflow. The connected documents refere...

shopify-scripts: Certain inputs cause tight C-level recursion leading to process stack overflow

Introduction ============ Certain legal Ruby programs can cause a tight recursion on the C-level without using eval while spending very little of the Ruby-level stack. This precludes triggering a Ruby stack overflow exception and eventually leads to a process stack overflow and a segfault. Both...
