• Product: Gentoo Security
• Status: RESOLVED INVALID

[Description John Helmert III 2021-12-15 23:58:36 UTC]

CVE-2021-40826 (https://voidsec.com/advisories/cve-2021-40826/):

Clementine Music Player through 1.3.1 is vulnerable to a User Mode Write Access Violation, affecting the MP3 file parsing functionality at clementine+0x3aa207. The vulnerability is triggered when the user opens a crafted MP3 file or loads a remote stream URL that is mishandled by Clementine. Attackers could exploit this issue to cause a crash (DoS) of the clementine.exe process or achieve arbitrary code execution in the context of the current logged-in Windows user.

CVE-2021-40827 (https://voidsec.com/advisories/cve-2021-40827/):

Clementine Music Player through 1.3.1 (when a GLib 2.0.0 DLL is used) is vulnerable to a Read Access Violation on Block Data Move, affecting the MP3 file parsing functionality at memcpy+0x265. The vulnerability is triggered when the user opens a crafted MP3 file or loads a remote stream URL that is mishandled by Clementine. Attackers could exploit this issue to cause a crash (DoS) of the clementine.exe process or achieve arbitrary code execution in the context of the current logged-in Windows user.


The reporter evidently didn't even test with debug symbols or provide
reproducers so can't tell if we're affected.

According to DarthGandalf on the Github PR, "The security bug affects only the windows build because it uses an old dependency in the installer. It probably can be closed already, but with the new release we can be 100% sure the old dependency is not there anymore"
