CVE-2024-22051: CWE-190 Integer Overflow or Wraparound
CommonMarker versions prior to 0.23.4 are at risk of an integer overflow vulnerability. This vulnerability can result in possibly unauthenticated remote attackers to cause heap memory corruption, potentially leading to an information leak or remote code execution, via parsing tables with marker rows that contain more than UINT16_MAX columns.
AI Analysis
Technical Summary
CVE-2024-22051 is an integer overflow vulnerability in CommonMarker before version 0.23.4. The issue arises when parsing tables with marker rows that have more columns than UINT16_MAX, causing an integer overflow or wraparound. This can lead to heap memory corruption, which attackers may exploit to leak information or execute arbitrary code remotely without authentication.
Potential Impact
Successful exploitation can result in heap memory corruption, enabling an unauthenticated remote attacker to potentially leak sensitive information or execute arbitrary code on the affected system. The vulnerability affects confidentiality, integrity, and availability, as reflected by the high CVSS score (9.8).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix is provided in the input data, users should monitor for vendor updates and apply any official fixes once available. Until then, avoid processing untrusted input that could trigger this vulnerability.
