Summary
libxml2 vulnerabilities
Details

Ahmed Lekssays discovered that libxml2 did not properly perform certain mathematical operations, leading to an integer overflow. An attacker could possibly use this issue to cause a crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-6021)

Ahmed Lekssays discovered that libxml2 did not properly validate the size of an untrusted input stream. An attacker could possibly use this issue to cause a crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-6170)

Nikita Sveshnikov discovered that libxml2 did not properly handle certain XPath expressions, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service. (CVE-2025-49794)

Nikita Sveshnikov discovered that libxml2 contained a type confusion vulnerability when parsing specially crafted XML documents. An attacker could potentially exploit this issue to cause a denial of service. (CVE-2025-49796)
