    # cmark-gfm: resource exhaustion due to quadratic complexity in parser *cmark-gfm* is GitHub's fork of *cmark*, a CommonMark parsing and rendering library and program in C. A polynomial time complexity issue in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service, due to quadratic complexity issues when parsing text which leads with either large numbers of `>` or `-` characters. The Haskell *cmark-gfm* package bundles the C sources and was affected by this issue. This fix was released in the upstream C package at version `0.29.0.gfm.10`. Version `0.2.6` of the Haskell package adopted the fix (moving from `0.29.0.gfm.6` to `0.29.0.gfm.13`). Packages that depend on *cmark-gfm* should update to `0.2.6` or later. Users unable to update should avoid processing data from untrusted sources or validate the input with other tools before using *cmark-gfm* to parse it. Pandoc `< 2.10.1` depended on *cmark-gfm* and could be affected by this issue.
