CVE-2023-43785: out-of-bounds memory access in _XkbReadKeySyms()
+
When libX11 is processing the reply from the X server to the XkbGetMap + request, if it detected the number of symbols in the new map was less + than the size of the buffer it had allocated, it always added room for + 128 more symbols, instead of the actual size needed. While the + _XkbReadBufferCopyKeySyms() helper function returned an error if asked + to copy more keysyms into the buffer than there was space allocated for, + the caller never checked for an error and assumed the full set of keysyms + was copied into the buffer and could then try to read out of bounds when + accessing the buffer. libX11 1.8.7 has been patched to both fix the size + allocated and check for error returns from _XkbReadBufferCopyKeySyms().
+
CVE-2023-43786: stack exhaustion in XPutImage
+
When splitting a single line of pixels into chunks that fit in a single + request (not using the BIG-REQUESTS extension) to send to the X server, + the code did not take into account the number of bits per pixel, so would + just loop forever finding it needed to send more pixels than fit in the + given request size and not breaking them down into a small enough chunk to + fit. An XPM file was provided that triggered this bug when loaded via + libXpm's XpmReadFileToPixmap() function, which in turn calls XPutImage() + and hit this bug.
+
CVE-2023-43787: integer overflow in XCreateImage() leading to a heap overflow
+
When creating an image, there was no validation that the multiplication + of the caller-provided width by the visual's bits_per_pixel did not + overflow and thus result in the allocation of a buffer too small to hold + the data that would be copied into it. An XPM file was provided that + triggered this bug when loaded via libXpm's XpmReadFileToPixmap() function, + which in turn calls XCreateImage() and hit this bug.i
