Alpine: multiple xwayland packages: security update to 24.1.7-r0

high Tenable Cloud Security Plugin ID 427888

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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.
(CVE-2025-49180)

- 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.
(CVE-2025-49175)

- 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.
(CVE-2025-49176)

- 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. (CVE-2025-49177)

- 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.
(CVE-2025-49178)
