-Subject: [PATCH] Validate lengths while parsing server data.
-
-Individual lengths inside received server data can overflow
-the previously reserved memory.
-
-It is therefore important to validate every single length
-field to not overflow the previously agreed sum of all invidual
-length fields.
-
-v2: consume remaining bytes in the reply buffer on error.

-Subject: [PATCH] Avoid OOB write in XRenderQueryFilters
-
-The memory for filter names is reserved right after receiving the reply.
-After that, filters are iterated and each individual filter name is
-stored in that reserved memory.
-
-The individual name lengths are not checked for validity, which means
-that a malicious server can reserve less memory than it will write to
-during each iteration.
-
-v2: consume remaining bytes in reply buffer on error.
