Subject: gweb: Fix OOB write in received_data()
|
|
|
|
There is a mismatch of handling binary vs. C-string data with memchr
|
|
and strlen, resulting in pos, count, and bytes_read to become out of
|
|
sync and result in a heap overflow. Instead, do not treat the buffer
|
|
as an ASCII C-string. We calculate the count based on the return value
|
|
of memchr, instead of strlen.
|
|
|
|
Fixes: CVE-2022-32292
