Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer Underwrite ('Buffer Underflow')

EUVDB-ID: #VU96897

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-45490

CWE-ID: CWE-124 - Buffer Underwrite ('Buffer Underflow')

Exploit availability: No

Description

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.

Mitigation

Update the affected package expat to the latest version.

2) Integer overflow

EUVDB-ID: #VU96898

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-45491

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the dtdCopy() function in xmlparse.c. A remote attacker can pass specially crafted input to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package expat to the latest version.
