Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU20904

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-13224

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the onig_new_deluxe() function in regext.c in Oniguruma library when processing regular expressions. A remote attacker can pass specially crafted input to the application using the vulnerable library version, trigger use-after-free error and perform denial of service attack or execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

Update the affected package oniguruma to the latest version.
