Severity: High
Title: libcue: Arbitrary Code Execution
Date: October 10, 2023
Bugs: #915500
ID: 202310-10
Synopsis
A vulnerability has been discovered in libcue which could allow for
arbitrary code execution.
Background
libcue is a CUE Sheet Parser Library.
Affected packages
Package Vulnerable Unaffected
media-libs/libcue < 2.2.1-r1 >= 2.2.1-r1
Description
libcue does not check bounds in a loop and suffers from an integer
overflow flaw which can be exploited to take over the program.
Impact
Untrusted CUE sheet files can lead to arbitrary code execution.
app-misc/tracker-miners[cue] uses libcue to index CUE Sheet files in
directories. It is possible that downloading a malicious CUE Sheet file
into a directory indexed by tracker-miners could lead to remote code
execution.
Workaround
There is no known workaround at this time.
Resolution
All libcue users should upgrade to the latest version:
emerge --sync
emerge --ask --oneshot --verbose “>=media-libs/libcue-2.2.1-r1”

A new security flaw has been disclosed in the libcue library impacting GNOME Linux systems that could be exploited to achieve remote code execution (RCE) on affected hosts. Tracked as CVE-2023-43641 (CVSS score: 8.8), the issue is described as a case of memory corruption in libcue, a library designed for parsing cue sheet files. It impacts versions 2.2.1 and prior. libcue is incorporated into
libcue provides an API for parsing and extracting data from CUE sheets. Versions 2.2.1 and prior are vulnerable to out-of-bounds array access. A user of the GNOME desktop environment can be exploited by downloading a cue sheet from a malicious webpage. Because the file is saved to `~/Downloads`, it is then automatically scanned by tracker-miners. And because it has a .cue filename extension, tracker-miners use libcue to parse the file. The file exploits the vulnerability in libcue to gain code execution.
