package/x11r7/xwayland: security bump to version 24.1.8
Fixes the following security issues:
- CVE-2025-49175: A flaw was found in the X Rendering extension's
handling of animated cursors. If a client provides no cursors, the
server assumes at least one is present, leading to an out-of-bounds
read and potential crash.
For more information, see:
- https://nvd.nist.gov/vuln/detail/CVE-2025-49175
- https://gitlab.freedesktop.org/xorg/xserver/-/commit/0885e0b2
- CVE-2025-49176: A flaw was found in the Big Requests extension. The
request length is multiplied by 4 before checking against the maximum
allowed size, potentially causing an integer overflow and bypassing
the size check.
For more information, see:
- https://nvd.nist.gov/vuln/detail/CVE-2025-49176
- https://gitlab.freedesktop.org/xorg/xserver/-/commit/03731b32
- CVE-2025-49177: A flaw was found in the XFIXES extension. The
XFixesSetClientDisconnectMode handler does not validate the request
length, allowing a client to read unintended memory from previous
requests.

- https://nvd.nist.gov/vuln/detail/CVE-2025-49177
- https://gitlab.freedesktop.org/xorg/xserver/-/commit/ab02fb96
- CVE-2025-49178: A flaw was found in the X server's request handling.
Non-zero 'bytes to ignore' in a client's request can cause the server
to skip processing another client's request, potentially leading to a
denial of service.
For more information, see:
- https://nvd.nist.gov/vuln/detail/CVE-2025-49178
- https://gitlab.freedesktop.org/xorg/xserver/-/commit/d55c54ce
- CVE-2025-49179: A flaw was found in the X Record extension. The
RecordSanityCheckRegisterClients function does not check for an
integer overflow when computing request length, which allows a client
to bypass length checks.
For more information, see:
- https://nvd.nist.gov/vuln/detail/CVE-2025-49179
- https://gitlab.freedesktop.org/xorg/xserver/-/commit/2bde9ca4
- CVE-2025-49180: A flaw was found in the RandR extension, where the
RRChangeProviderProperty function does not properly validate input.
This issue leads to an integer overflow when computing the total size
to allocate.
