GLSA-202401-21 : KTextEditor: Arbitrary Local Code Execution

high Nessus Plugin ID 188050

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202401-21 (KTextEditor: Arbitrary Local Code Execution)

 - The LSP (Language Server Protocol) plugin in KDE Kate before 21.12.2 and KTextEditor before 5.91.0 tries to execute the associated LSP server binary when opening a file of a given type. If this binary is absent from the PATH, it will try running the LSP server binary in the directory of the file that was just opened (due to a misunderstanding of the QProcess API, that was never intended). This can be an untrusted directory. (CVE-2022-23853)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All KTextEditor users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=kde-frameworks/ktexteditor-5.90.0-r2
