Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-52425)

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 when parsing large tokens. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Buffer Underwrite ('Buffer Underflow') (CVE-ID: CVE-2024-45490)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to a boundary error in xmlparse.c when handling negative length for XML_ParseBuffer. A remote attacker can pass specially crafted input to the application, trigger buffer underflow and execute arbitrary code on the system.


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.


5) NULL pointer dereference (CVE-ID: CVE-2024-36387)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error when handling websocket over HTTP/2 connections. A remote attacker can send specially crafted data to the web server and perform a denial of service (DoS) attack.


6) Out-of-bounds read (CVE-ID: CVE-2024-5535)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the SSL_select_next_proto() function when using NPN. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.
