Summary
libxml2 vulnerabilities
Details

It was discovered that the libxml2 Python bindings incorrectly handled certain return values. An attacker could possibly use this issue to cause libxml2 to crash, resulting in a denial of service. (CVE-2025-32414)

It was discovered that libxml2 incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause libxml2 to crash, resulting in a denial of service. (CVE-2025-32415)

It was discovered that libxslt, used by libxml2, incorrectly handled certain attributes. An attacker could use this issue to cause a crash, resulting in a denial of service, or possibly execute arbitrary code. This update adds a fix to libxml2 to mitigate the libxslt vulnerability. (CVE-2025-7425)
