CVE-2023-22485 is fixed in 4 products on 1 platform, first by DEBIAN-CVE-2023-22485, released January 24, 2023. It is not reported as exploited. Patch Radar priority: Routine.
cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior 0.29.0.gfm.7, a crafted markdown document can trigger an out-of-bounds read in the `validate_protocol` function. We believe this bug is harmless in practice, because the out-of-bounds read accesses `malloc` metadata without causing any visible damage.This vulnerability has been patched in 0.29.0.gfm.7.
