Vulnerability CVE-2018-10992

Vulnerability Name:

CVE-2018-10992 (CCN-143261)

Assigned:

2018-05-10

Published:

2018-05-10

Updated:

2020-08-24

Summary:

lilypond-invoke-editor in LilyPond 2.19.80 does not validate strings before launching the program specified by the BROWSER environment variable, which allows remote attackers to conduct argument-injection attacks via a crafted URL, as demonstrated by a --proxy-pac-file argument, because the GNU Guile code uses the system Scheme procedure instead of the system* Scheme procedure.
Note: this vulnerability exists because of an incomplete fix for CVE-2017-17523.
