|
||||
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.

|
||||
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.

Fix documentation to explicitly mention premultiplied alpha
|
||||
|
||||
Before this patch, it wasn't mentioned in this file at all, which
|
||||
is a monumental oversight.
