CVSS: 7.8EPSS: 87%CPEs: 4EXPL: 16CVE-2019-18634 – Sudo 1.8.25p - 'pwfeedback' Buffer Overflow (PoC)
https://notcve.org/view.php?id=CVE-2019-18634
29 Jan 2020 — In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. (pwfeedback is a default setting in Linux Mint and elementary OS; however, it is NOT the default for upstream and many other packages, and would exist only if enabled by an administrator.) The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c. En Sudo anterior a la versión 1.8.26, si pwfeedback está habilitado en / etc / sudoers, los usu... • https://packetstorm.news/files/id/156189 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

04 Nov 2019 — Sudo through 1.8.29 allows local users to escalate to root if they have write access to file descriptor 3 of the sudo process. This occurs because of a race condition between determining a uid, and the setresuid and openat system calls. The attacker can write "ALL ALL=(ALL) NOPASSWD:ALL" to /proc/#####/fd/3 at a time when Sudo is prompting for a password. NOTE: This has been disputed due to the way Linux /proc works. It has been argued that writing to /proc/#####/fd/3 would only be viable if you had permiss... • https://gist.github.com/oxagast/51171aa161074188a11d96cbef884bbd • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

15 Oct 2019 — In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro... • https://www.exploit-db.com/exploits/47502 • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •
