CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the xmlSchematronGetNode() function when processing XPath expressions in Schematron schema elements schematron.c. A remote attacker can pass specially crafted XML input to the application and perform a denial of service (DoS) attack.
2) Type Confusion (CVE-ID: CVE-2025-49796)
CWE-ID: CWE-843 - Type confusion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error within the xmlSchematronFormatReport() function when processing sch:name elements in schematron.c. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and crash the application.
3) Integer overflow (CVE-ID: CVE-2025-6021)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
