EUVDB-ID: #VU32570
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2014-0017
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a local non-authenticated attacker to gain access to sensitive information.
The RAND_bytes function in libssh before 0.6.3, when forking is enabled, does not properly reset the state of the OpenSSL pseudo-random number generator (PRNG), which causes the state to be shared between children processes and allows local users to obtain sensitive information by leveraging a pid collision.
MitigationInstall update from vendor's website.
Vulnerable software versionslibssh: 0.6.0 - 0.6.1
