Detailsinfo

A vulnerability was found in shadow and sudo (Operating System Utility Software) (affected version not known). It has been classified as critical. This affects some unknown functionality of the component Session Handler. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process.

The weakness was published 11/04/2019. This vulnerability is uniquely identified as CVE-2005-4890 since 12/19/2011. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 74628 (openSUSE Security Update : coreutils (openSUSE-SU-2012:0621-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (74628) and OSVDB (94040†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
