CVE-2022-24724 Integer overflow in table parsing extension leads to heap memory corruption
PublishedCriticalCVSS 9.8cmark-gfm is GitHub's extended version of the C reference implementation of CommonMark. Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm's table row parsing table.c:row_from_string may lead to heap memory corruption when parsing tables who's mark...

MediumCVSS 6.5
The table extension in GitHub Flavored Markdown before version 0.29.0.gfm.1 takes O(n * n) time to parse certain inputs. An attacker could craft a markdown table which would take an unreasonably long time to process, causing a denial of service. This issue does not affect the ups...
