Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2024-8176)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling XML content. A remote attacker can pass specially crafted XML content to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Resource exhaustion (CVE-ID: CVE-2025-59375)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger large dynamic memory allocations via a small document and perform a denial of service (DoS) attack.
3) Use-after-free (CVE-ID: CVE-2025-49794)
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.
4) Stack-based buffer overflow (CVE-ID: CVE-2025-6170)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in xmllint Shell - shell.c. A remote attacker can pass specially crafted input to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Integer overflow (CVE-ID: CVE-2025-6021)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the xmlBuildQName() function in tree.c . A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Type Confusion (CVE-ID: CVE-2025-49796)
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.
7) Use-after-free (CVE-ID: CVE-2025-10911)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error when parsing xsl nodes. A remote attacker can pass a specially crafted XML file to the application and crash it.
8) Use-after-free (CVE-ID: CVE-2025-7425)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xsltSetSourceNodeFlags() function. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
9) Type Confusion (CVE-ID: CVE-2025-11731)
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 exsltFuncResultComp() function when handling EXSLT elements during stylesheet parsing. A remote attacker can pass specially crafted XML data to the application, trigger a type confusion error and perform a denial of service (DoS) attack.
10) Use-after-free (CVE-ID: CVE-2024-55549)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in xsltGetInheritedNsList. A remote attacker can pass specially crafted input to the application, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
