details: The commonmark package, specifically in its dependency on GitHub Flavored Markdown before version 0.29.0.gfm.1, | ||
has a vulnerability related to time complexity. Parsing certain crafted markdown tables can take O(n * n) time, | ||
leading to potential Denial of Service attacks. This issue does not affect the upstream cmark project and has been | ||
fixed in version 0.29.0.gfm.1. | ||

details: cmark-gfm, GitHub's extended CommonMark library, has multiple vulnerabilities. Versions prior to 0.29.0.gfm.6 | ||
suffer from a polynomial time complexity issue in the autolink extension, causing denial of service. Also, versions | ||
before 0.29.0.gfm.3 and 0.28.3.gfm.21 contain an integer overflow in table row parsing, leading to heap corruption and | ||
potential Arbitrary Code Execution. Patches are available in versions 0.29.0.gfm.6, 0.29.0.gfm.3, and 0.28.3.gfm.21. | ||
Mitigations include upgrading or disabling affected extensions. | ||

details: cmark-gfm, GitHub's extended version of the CommonMark library in C, suffers from multiple vulnerabilities | ||
affecting versions prior to 0.29.0.gfm.12. Various issues, including polynomial time complexity in multiple components | ||
like autolink extension, handle_close_bracket, and parsing of certain text patterns (leading `>`, `-`, `_`), may lead | ||
to unbounded resource exhaustion and denial of service. An out-of-bounds read in the `validate_protocol` function was | ||
also identified but is considered less harmful. Patches are available in versions 0.29.0.gfm.7, 0.29.0.gfm.10, and | ||
0.29.0.gfm.12. Upgrading is advised, and users unable to upgrade should validate input from trusted sources. | ||
