Summary
libxml2 vulnerabilities
Details

It was discovered that libxml2 incorrectly handled certain memory operations. A remote attacker could use this issue to cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-49043)

It was discovered that the libxml2 xmllint tool incorrectly handled certain memory operations. If a user or automated system were tricked into running xmllint on a specially crafted xml file, a remote attacker could cause xmllint to crash, resulting in a denial of service. (CVE-2024-34459)
