Security Advisory

This security advisory describes one low risk vulnerability.

1) Heap-based buffer overflow

Severity: Low

CVSSv3: 6.7 [CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C] [PCI]

CVE-ID: CVE-2019-18218

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the cdf_read_property_info() function in cdf.c in file due to improper restrictions of the number of CDF_VECTOR elements. A local user can place a specially crafted CDF (Composite Document File) file on the system, trick the victim into reading it with the affected software, trigger heap-based buffer overflow (4-byte out-of-bounds write) and execute arbitrary code on the target system with elevated privileges.

Mitigation

Update the affected packages.
