-Subject: [PATCH] Protocol handling issues in libXv - CVE-2016-5407
-
-The Xv query functions for adaptors and encodings suffer from out of
-boundary accesses if a hostile X server sends a maliciously crafted
-response.
-
-A previous fix already checks the received length against fixed values
-but ignores additional length specifications which are stored inside
-the received data.
-
-These lengths are accessed in a for-loop. The easiest way to guarantee
-a correct processing is by validating all lengths against the
-remaining size left before accessing referenced memory.
-
-This makes the previously applied check obsolete, therefore I removed
-it.
