Subject: [PATCH] Mail: fixed clearing s->passwd in auth http requests.
|
|
|
|
Previously, it was not properly cleared retaining length as part of
|
|
authenticating with CRAM-MD5 and APOP methods that expect to receive
|
|
password in auth response. This resulted in null pointer dereference
|
|
and worker process crash in subsequent auth attempts with CRAM-MD5.
|
|
|
|
Reported by Arkadi Vainbrand.
|
|
|
|
(cherry picked from commit 0f71dd8ea94ab8c123413b2e465be12a35392e9c)
