Alpine: multiple xwayland packages: security update to 23.2.5-r0
high Tenable Cloud Security Plugin ID 427119
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents()
function. This issue occurs when byte-swapped length values are used in replies, potentially leading to
memory leakage and segmentation faults, particularly when triggered by a client with a different
endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory
values and then transmit them back to the client until encountering an unmapped page, resulting in a
crash. Despite the attacker's inability to control the specific memory copied into the replies, the small
length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds
reads. (CVE-2024-31080)
- A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIPassiveGrabDevice()
function. This issue occurs when byte-swapped length values are used in replies, potentially leading to
memory leakage and segmentation faults, particularly when triggered by a client with a different
endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory
values and then transmit them back to the client until encountering an unmapped page, resulting in a
crash. Despite the attacker's inability to control the specific memory copied into the replies, the small
length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds
reads. (CVE-2024-31081)
- A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue
occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially
resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently,
ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer
is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the
system by sending a specially crafted request. (CVE-2024-31083)
