DATE CVE VULNERABILITY TITLE RISK
2016-01-19 CVE-2016-1907 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Openbsd Openssh
The ssh_packet_read_poll2 function in packet.c in OpenSSH before 7.1p2 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic.

2016-01-14 CVE-2016-0778 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
The (1) roaming_read and (2) roaming_write functions in roaming_common.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 buffer overflow) or possibly have unspecified other impact by requesting many forwardings.

2016-01-14 CVE-2016-0777 Information Exposure vulnerability in multiple products
The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.

6.5
2014-03-18 CVE-2014-2532 Permissions, Privileges, and Access Controls vulnerability in multiple products
sshd in OpenSSH before 6.6 does not properly support wildcards on AcceptEnv lines in sshd_config, which allows remote attackers to bypass intended environment restrictions by using a substring located before a wildcard character.

4.9
2006-09-27 CVE-2006-5051 Double Free vulnerability in multiple products
Signal handler race condition in OpenSSH before 4.4 allows remote attackers to cause a denial of service (crash), and possibly execute arbitrary code if GSSAPI authentication is enabled, via unspecified vectors that lead to a double-free.

8.1
2004-11-23 CVE-2004-0079 NULL Pointer Dereference vulnerability in multiple products
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
7.5
2003-08-27 CVE-2003-0466 Off-by-one Error vulnerability in multiple products
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.

2002-08-12 CVE-2002-0391 Integer Overflow or Wraparound vulnerability in multiple products
Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
