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.
