Comment 4 Pedro Monreal Gonzalez 2023-07-21 09:31:37 UTC

pcre2 with version 10.x is affected. Note that, this is an infinite loop in the CLI tool, so there is no real security impact.

pcre with version 8.x doesn't seem to be affected by this CVE.

I agree with you. There is a similar loop in in pcre/pcretest.c:

while (dbuffer == NULL || (size_t)len >= dbuffer_size)
      {
      dbuffer_size *= 2;
      dbuffer = (pcre_uint8 *)realloc(dbuffer, dbuffer_size * CHAR_SIZE);
      if (dbuffer == NULL)
        {
        fprintf(stderr, "pcretest: realloc(%d) failed\n", (int)dbuffer_size);
        exit(1);
        }
      }

But as far as I see, (size_t)len can't be arbitrary set to 2^64.
