CVE-2024-35333: Stack buffer overflow in html2xhtml 1.3. Exploitable via crafted input to the read_charset_decl function.

CVE-2024-35333 is a critical vulnerability in html2xhtml 1.3, specifically a stack buffer overflow in the read_charset_decl function. Due to insufficient bounds checking, a specially crafted input can cause a buffer overflow, potentially leading to arbitrary code execution. Despite a CVSS score of 8.4 indicating high severity, the SOCRadar Vulnerability Risk Score (SVRS) is 30, suggesting a lower real-world risk than the CVSS score alone suggests. While the CVSS score indicates a significant threat and is tagged as In The Wild, the SVRS tempers this by indicating its potential real-world exploitability is somewhat mitigated. Organizations using html2xhtml should still address this vulnerability, even with the lower SVRS, given the potential for denial of service or code execution.
