Alpine: multiple xorg-server packages: security update to 21.1.9-r0
high Tenable Self-Hosted Container Security Plugin ID 407934
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect
calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function
in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible
escalation of privileges or denial of service. (CVE-2023-5367)
- A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and
legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if
the pointer is warped from within a window on one screen to the root window of the other screen and if the
original window is destroyed followed by another window being destroyed. (CVE-2023-5380)
- A use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with a very specific
and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode).
If the pointer is warped from a screen 1 to a screen 0, a use-after-free issue may be triggered during
shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service.
