EUVDB-ID: #VU65553

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

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.
