Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU104099
Risk: High
CVSSv4.0: 8.1 [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]
CVE-ID: CVE-2024-56171
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package libxml2 to the latest version.

2) Stack-based buffer overflow
EUVDB-ID: #VU104098
Risk: High
CVSSv4.0: 8.1 [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]
CVE-ID: CVE-2025-24928
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package libxml2 to the latest version.
