Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU29116

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-20454

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition in the "do_extuni_no_utf in pcre2_jit_compile.c" file when the pattern X is JIT compiled and used to match specially crafted subjects in non-UTF mode. A remote attacker can trigger out-of-bounds read error and crash the affected application.

Mitigation

Update the affected package pcre2 to the latest version.

2) Out-of-bounds read

EUVDB-ID: #VU65553

Risk: Medium

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

CVE-ID: CVE-2022-1587

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the get_recurse_data_length() function in pcre2_jit_compile.c when handling recursions in JIT-compiled regular expressions. A remote attacker can pass specially crafted input to the affected application, trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package pcre2 to the latest version.
