EulerOS Virtualization for ARM 64 3.0.2.0 : sudo (EulerOS-SA-2020-1564)
high Nessus Plugin ID 136267
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.Description
According to the versions of the sudo package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :- In PHP before 5.6.28 and 7.x before 7.0.13, incorrect handling of various URI components in the URL parser could be used by attackers to bypass hostname-specific URL checks, as demonstrated by evil.example.com:80#@good.example.com/ and evil.example.com:[email protected]/ inputs to the parse_url function (implemented in the php_url_parse_ex function in ext/standard/url.c).(CVE-2019-19234)
- In Sudo through 1.8.29, the fact that a user has been blocked (e.g., by using the ! character in the shadow file instead of a password hash) is not considered, allowing an attacker (who has access to a Runas ALL sudoer account) to impersonate any blocked user.(CVE-2019-19232)
- 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.(CVE-2019-18634)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
