Security researchers from Qualys discovered a new vulnerability in sudo which allows unauthenticated attackers to gain root privileges. The attacker needs to have access to the system as a user to exploit this vulnerability but once they are logged-in they do not need to provide any further authentication password to escalate their privilege to root.

The vulnerable code that causes the Heap-based buffer overflow was introduced in sudo version 1.8.2.

SUSE Linux Enterprise Server 12 and SUSE Linux Enterprise Server 15 products are affected.
SUSE Linux Enterprise Server 11 products are not affected.



Fixes have been provided for the affected supported products.
