| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
OpenSSH versions prior to 7.4
Description
The issue is related to a buffer overflow in the shared memory manager of the sshd daemon in OpenSSH, which can be exploited by a local attacker to gain privileges. This is achieved by leveraging access to a sandboxed privilege-separation process, specifically related to the
m zback and m zlib data structures.Recommendations
For versions prior to 7.4, update to version 7.4 or later to resolve the issue.
As a temporary workaround, consider restricting access to the privilege-separation process to minimize the risk of exploitation.
