Summary

tcl security update

Details

Tcl(Tool Command Language) provides a powerful platform for creating integration applications that tie together diverse applications, protocols, devices, and frameworks. When paired with the Tk toolkit, Tcl provides the fastest and most powerful way to create GUI applications that run on linux, Unix, and Mac OS X. Tcl can also be used for a variety of web-related tasks and for creating powerful command languages for applications.

Security Fix(es):

** DISPUTED ** In Tcl 8.6.11, a format string vulnerability in nmakehlp.c might allow code execution via a crafted file. NOTE: multiple third parties dispute the significance of this finding.(CVE-2021-35331)

Severity

7.8 (High)
