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
DescriptionThe 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.
