5.3

Medium

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Name of the Vulnerable Software and Affected Versions libssh (affected versions not specified)
Description A flaw was found in the libssh implementation of an abstract layer for message digest (MD) operations. The return values from these operations were not properly checked, which could cause low-memory situation failures, NULL dereferences, crashes, or usage of uninitialized memory as an input for the Key Derivation Function (KDF). This could result in decryption/integrity failures, terminating the connection. The issue may allow a remote attacker to cause a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
