SB2025051314 - Multiple vulnerabilities in IBM App Connect Enterprise Certified Container

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) 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.

2) 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.

3) Use-after-free (CVE-ID: CVE-2025-24855)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in numbers.c when handling nested XPath evaluations. A remote attacker can pass specially crafted XML 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.

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) Out-of-bounds write (CVE-ID: CVE-2025-27363)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can pass a specially crafted font to the application that is using an affected version of the library, trigger an out-of-bounds write and execute arbitrary code on the target system.
