Bug ID: 56210
Summary: Possible null deference in
apache/modules/ssl/ssl_util.c
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: Mac OS X 10.4
Status: NEW
Severity: normal
Priority: P2
Component: mod_ssl
Assignee: [email protected]
Reporter: [email protected]
I found a weird struct declaration in function ssl_util_thr_id as we can see
bellow. Several tools are pointing to possible null deference at line (return
psaptr->PSATOLD;).
static unsigned long ssl_util_thr_id(void)
{
/* OpenSSL needs this to return an unsigned long. On OS/390, the pthread
* id is a structure twice that big. Use the TCB pointer instead as a
* unique unsigned long.
*/
#ifdef __MVS__
struct PSA {
char unmapped[540];
unsigned long PSATOLD;
} *psaptr = 0;
return psaptr->PSATOLD;
#else
return (unsigned long) apr_os_thread_current();
#endif
}
