libcue Library Flaw Opens GNOME Linux Systems Vulnerable to RCE Attacks

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

CVE-2023-43641: Coordinated Disclosure: 1-Click RCE on GNOME (CVE-2023-43641)

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.
