Summary

popt security update

Details

The popt library exists essentially for parsing command line options. Some specific advantages of popt are no global variables (allowing multiple passes in parsing argv), parsing an arbitrary array of argv-style elements (allowing parsing of command-line-strings from any source), a standard method of option aliasing, ability to exec external option filters, and automatic generation of help and usage messages.

Security Fix(es):

An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application.(CVE-2026-18839)
