Reported By: Maylein at ub dot uni-heidelberg dot de
Status: Assigned
Bug Type: IMAP related
Operating System: *
PHP Version: 5.2.6
Assigned To: pajoye
New Comment:
Looking at the current code, it looks like there's no actual overflow,
but rfc822_write_address is limited so the abort happens. I am not
seeing code path that would lead to rfc822_write_address writing more
data than buffer size, unless I misunderstand how _php_imap_address_size
works.
Is this impression correct? If so, we still need to fix it since
abort() is a nasty things, but it doesn't seem to be a security issue.

I will give it some love while working on the imap lib.

please fix 008_imap-bufferoverflows.patch to include the typedef for
RFC822BUFFER.
/* Output buffering for RFC [2]822 */
typedef long (*soutr_t) (void *stream,char *string);
typedef struct rfc822buffer {
soutr_t f; /* I/O flush routine */
void *s; /* stream for I/O routine */
char *beg; /* start of buffer */
char *cur; /* current buffer pointer */
char *end; /* end of buffer */
} RFC822BUFFER;

Over 7 months and two releases have passed, yet no developer even
commented on this *security* issue (according to the c-client devs). So
what's up with this, are there any problems with the patch? If yes,
would you mind pointing them out, so that one can try to fix them?

I use Horde Groupware Webmail Edition 1.0.6 with Apache/1.3.41 (Unix)
PHP/5.2.5 mod_ssl/2.8.31 OpenSSL/0.9.8g.
I had the same bug.
I tried sborril patch: it fix the problem also in my environment. I
appreciate if could be added to next release of php.
Regards
