Last modified

CVE-2024-48991 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Qualys discovered that needrestart, before version 3.8, allows local attackers to execute arbitrary code as root by winning a race condition and tricking needrestart into running their own, fake Python interpreter (instead of the system's real Python interpreter). The initial security fix (6ce6136) introduced a regression which was subsequently resolved (42af5d3).. EPSS estimates a 5.29% chance of exploitation in the next 30 days.
