CVE-2025-4878
Good to know:
Date: July 22, 2025
In libssh before 0.11.2 the privatekey_from_file() uses an uninitialized variable under certain conditions, such as if the file specified by the filename argument doesn't exist. This causes the code to return an invalid private key. This defect, in turn, might cause signing failure. The bug might also cause a Use-After-Free or corrupt the heap.
