2022-07-18fix coredumps in XRenderComputeTrapezoids (issue #1)Dmitry Karasik
Rationale: I don't have enough expertise to judge on how the tessellation algorithm is broken in XRenderComputeTrapezoids but I do trust Keith Packard that it is. However using cairo for proper tessellation, as he suggests, is too heavyweight, and here I propose to alter the code to at least do not cause coredumps. Even if/when the function will be marked as obsolete, I believe it is pretty much capable of rendering relatively simple shapes, and still retains some value.

2016-09-25Validate lengths while parsing server data.Tobias Stoeckmann
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.

2016-09-25Avoid OOB write in XRenderQueryFiltersTobias Stoeckmann
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.

2013-11-23Fix request length calculation for XRenderCompositeText32Clemens Eisserer
Request length calculation inside XRenderCompositeText32 is broken for the case where the number of glyphs fits exactky inside the last xGlyphElt. In XRenderCompositeText8 and XRenderCompositeText16 this case is handled properly, somehow the "-1" got missing in XRenderCompositeText32. Reviewed-by: Keith Packard <keithp@keithp.com>
2013-11-22Remove fallback for _XEatDataWords, require libX11 1.6 for itMichael Joost
_XEatDataWords was orignally introduced with the May 2013 security patches, and in order to ease the process of delivering those, fallback versions of _XEatDataWords were included in the X extension library patches so they could be applied to older versions that didn't have libX11 1.6 yet. Now that we're past that hurdle, we can drop the fallbacks and just require libX11 1.6 for building new versions of the extension libraries.
