MGASA-2023-0325 - Updated lilypond packages fix a security vulnerability

Publication date: 27 Nov 2023
URL: https://advisories.mageia.org/MGASA-2023-0325.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2020-17354

Updated lilypond packages fix a security vulnerability:

LilyPond before 2.24 allows attackers to bypass the -dsafe protection
mechanism via output-def-lookup or output-def-scope, as demonstrated by
dangerous Scheme code in a .ly file that causes arbitrary code execution
during conversion to a different file format. NOTE: in 2.24 and later
versions, safe mode is removed, and the product no longer tries to block
code execution when external files are used.
