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 containing more than UINT16_MAX columns, causing an integer overflow or wraparound. This can lead to heap memory corruption, which may be exploited by unauthenticated remote attackers to achieve information leakage or remote code execution. The vulnerability is classified under CWE-190 and has a critical CVSS 3.1 score of 9.8, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can result in heap memory corruption, enabling attackers to leak sensitive information or execute arbitrary code remotely without authentication. This poses a critical risk to affected systems running vulnerable CommonMarker versions.
Mitigation Recommendations
Upgrade CommonMarker to version 0.23.4 or later, where this integer overflow vulnerability is fixed. No other mitigations are indicated by the vendor advisory.
