Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU9542
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-16932
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in parser.c function due to improper handling of certain parameter entities. A remote attacker can supply specially constructed XML data, trigger resource exhaustion and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
Update the affected package libxml2 to the latest version.

2) Integer overflow
EUVDB-ID: #VU62741
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-2022-29824
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*). A remote attacker can pass specially crafted multi-gigabyte XML file to the application, trigger integer 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.
