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.
