![]() They said that are UNIX-like operating systems are also impacted, but most security researchers thought the bug might impact BSD, another major OS that also ships with the Sudo app. From a report: The vulnerability, which received a CVE identifier of CVE-2021-3156, but is. A major vulnerability impacting a large chunk of the Linux ecosystem has been patched today in Sudo, an app that allows admins to delegate limited root access to other users. In their report last week, Qualys researchers said they only tested the issue on Ubuntu, Debian, and Fedora. 10-year-old Sudo Bug Lets Linux Users Gain Root-Level Access () 166. The two previous bugs, CVE-2019-14287 (known as the -1 UID bug) and CVE-2019-18634 (known as the pwfeedback bug), were hard to exploit because they required complex and non-standard sudo setups. The only condition to exploit this bug was that an attacker gain access to a system, which researchers said could be done by either planting malware on a device or brute-forcing a low-privileged service account. If exploited, the bug could lead to privilege escalation to. The original description indicated that the vulnerability is a heap-based buffer overflow, affecting Sudo before 1.9.5p2. Only minor changes to the original exploit are needed to exploit the bug on macOS. previously posted in the Linux Users Group : '10-year. Researcher Matthew Hickey says that the CVE-2021-3156 bug also impacts macOS. A bug in the Sudo app can let attackers with access to a local system to elevate their access to a root-level account. Qualys researchers discovered that they could trigger a 'heap overflow' bug in the Sudo app to change the current user's low-privileged access to root-level commands, granting the attacker access to the whole system. Recent root-giving Sudo bug also impacts macOS. And mixing alpha-numeric characters also impacts performance. From a report: The vulnerability, disclosed last week as CVE-2021-3156 (aka Baron Samedit) by security researchers from Qualys, impacts Sudo, an app that allows admins to delegate limited root access to other users. bug bounties, bug auctions, competitions, or other inducements. A British security researcher has discovered this week that a recent security flaw in the Sudo app also impacts the macOS operating system, and not just Linux and BSD, as initially believed. ![]()
