Siemens SCALANCE X-200RNA Switch Devices Improper Input Validation (CVE-2015-6563)

The monitor component in sshd in OpenSSH before 7.0 on non-OpenBSD platforms accepts extraneous username data in MONITORREQPAMINITCTX requests, which allows local users to conduct impersonation attacks by leveraging any SSH login access in conjunction with control of the sshd uid to send a crafte...

Siemens SCALANCE X-200RNA Switch Devices Improper Restriction of Operations within the Bounds of a Memory Buffer (CVE-2016-0778)

The 1 roamingread and 2 roamingwrite functions in roamingcommon.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service heap-based...

Siemens SCALANCE X-200RNA Switch Devices Exposure of Sensitive Information to an Unauthorized Actor (CVE-2016-6210)

sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is...

Siemens SCALANCE X-200RNA Switch Devices Improper Restriction of Operations within the Bounds of a Memory Buffer (CVE-2016-10012)

The shared memory manager associated with pre-authentication compression in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to t...

Siemens SCALANCE X-200RNA Switch Devices Improper Authentication (CVE-2016-1908)

The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues ...

Siemens SCALANCE X-200RNA Switch Devices Concurrent Execution Using Shared Resource with Improper Synchronization (CVE-2003-1562)

sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password...

VulnCheck KEV: CVE-2024-6409

A race condition vulnerability was discovered in how signals are handled by OpenSSH's server sshd. If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not...
