Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU68111

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-6004

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the compile_bracket_matchingpath() function in pcre_jit_compile.c. A remote attacker can pass a specially crafted regular expression to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.

Mitigation

Update the affected package pcre to the latest version.
