http://security.gentoo.org/

Severity:	high
Title:	libcue: Arbitrary Code Execution
Date:	10/10/2023
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	Architecture(s)
media-libs/libcue	< 2.2.1-r1	>= 2.2.1-r1	All supported architectures

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"
