Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2025-22868)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the jws package does not properly control consumption of internal resources when handling malformed tokens. A remote attacker can pass a malformed JWT token to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2025-22869)

3) Use-after-free (CVE-ID: CVE-2024-56171)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xmlSchemaIDCFillNodeTables() and xmlSchemaBubbleIDCNodeTables() functions in xmlschemas.c. A remote attacker can pass specially crafted XML document 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.
4) Stack-based buffer overflow (CVE-ID: CVE-2025-24928)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the xmlSnprintfElements() function in valid.c. A remote attacker can pass specially crafted XML data 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.
