Notes

Topic
An update for pandoc is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Pandoc is a markdown/markup conversion tool. The version of pandoc in RHEL 8 CRB uses cmark-gfm (GitHub's extended version of the C reference implementation of CommonMark) for parts of its conversion. The update, fixes CVE-2022-24724: an integer overflow in cmark-gfm's table row parsing which may lead to heap memory corruption when parsing tables with more than UINT16_MAX columns. Security Fix(es): * cmark-gfm: possible RCE due to integer overflow (CVE-2022-24724) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm\u0027s table row parsing `table.c:row_from_string` may lead to heap memory corruption when parsing tables who\u0027s marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution depending on how and where `cmark-gfm` is used. If `cmark-gfm` is used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE) in applications employing affected versions of the `cmark-gfm` library. This vulnerability has been patched in the following cmark-gfm versions 0.29.0.gfm.3 and 0.28.3.gfm.21. A workaround is available. The vulnerability exists in the table markdown extensions of cmark-gfm. Disabling the table extension will prevent this vulnerability from being triggered.",
