Gentoo Linux Security Advisory 202310-10 - A vulnerability has been discovered in libcue which could allow for arbitrary code execution. Versions greater than or equal to 2.2.1-r1 are affected.
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.
