Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU32412

Risk: High

CVSSv3.1: 7.9 [AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-5073

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38. A remote attacker can use a crafted regular expression with an excess closing parenthesis. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

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

2) Use of uninitialized resource

EUVDB-ID: #VU77578

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-8390

CWE-ID: CWE-908 - Use of Uninitialized Resource

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources when processing the [: and \ substrings in character classes. A remote attacker can pass specially crafted data to the application, trigger uninitialized usage of resources and bypass implemented security mechanisms.
