Bug ID: 2090
Summary: Suspicious sequence of types castings: memsize ->
32-bit integer -> memsize
Product: PCRE
Version: 10.23 (PCRE2)
Hardware: x86-64
OS: All
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: p...@hermes.cam.ac.uk
Reporter: egor...@gmail.com
CC: pcre-dev@exim.org
Suspicious sequence of types castings: memsize -> 32-bit integer -> memsize.
The value being cast: '(p - string)'. pcre2_valid_utf.c
See lines 145, 151, 158
I suppose instead of casting to int:
*erroroffset = (int)(p - string);
casting to PCRE2_SIZE should be implemented:
*erroroffset = (PCRE2_SIZE)(p - string);
