HighExploitation Probability (EPSS)
Low risk49th percentile - higher than 49% of all known CVEs
Summary
A buffer overflow vulnerability was found in the ncurses library that allows a local user to execute arbitrary commands via long environmental variables such as TERM or TERMINFO_DIRS.
Risk Assessment
A local user can escalate privileges and execute arbitrary code in the context of a process using ncurses, potentially compromising system security.
Recommendation
Update the ncurses library to the latest version that fixes this vulnerability. Restrict local access to trusted users only.
