FreeBSD -- OpenSSH pre-authentication double free

Problem Description: A flaw in the backwards-compatibility key exchange route allows a pointer to be freed twice. Impact: A remote, unauthenticated attacker may be able to cause a denial of service, or possibly remote code execution. Note that FreeBSD 12.3 and FreeBSD 13.1 include older versions ...

SUSE CVE-2003-0695

Multiple "buffer management errors" in OpenSSH before 3.7.1 may allow attackers to cause a denial of service or execute arbitrary code using 1 bufferinit in buffer.c, 2 bufferfree in buffer.c, or 3 a separate function in channels.c, a different vulnerability than CVE-2003-0693...

SUSE CVE-2003-0786

The SSH1 PAM challenge response authentication in OpenSSH 3.7.1 and 3.7.1p1, when Privilege Separation is disabled, does not check the result of the authentication attempt, which can allow remote attackers to gain privileges...

SUSE CVE-2003-0787

The PAM conversation function in OpenSSH 3.7.1 and 3.7.1p1 interprets an array of structures as an array of pointers, which allows attackers to modify the stack and possibly gain privileges...

SUSE CVE-2004-0175

Directory traversal vulnerability in scp for OpenSSH before 3.4p1 allows remote malicious servers to overwrite arbitrary files. NOTE: this may be a rediscovery of CVE-2000-0992...

SUSE CVE-2004-2069

sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to...

SUSE CVE-2004-2760

sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by...

SUSE CVE-2005-2798

sshd in OpenSSH before 4.2, when GSSAPIDelegateCredentials is enabled, allows GSSAPI credentials to be delegated to clients who log in using non-GSSAPI methods, which could cause those credentials to be exposed to untrusted users or hosts...

packet.c in ssh in OpenSSH allows remote attackers to cause a denial of service crash by sending an invalid protocol sequence with USERAUTHSUCCESS before NEWKEYS, which causes newkeysmode to be NULL...

SUSE CVE-2006-4924

sshd in OpenSSH before 4.4, when using the version 1 SSH protocol, allows remote attackers to cause a denial of service CPU consumption via an SSH packet that contains duplicate blocks, which is not properly handled by the CRC compensation attack detector...

SUSE CVE-2006-5052

Unspecified vulnerability in portable OpenSSH before 4.4, when running on some platforms, allows remote attackers to determine the validity of usernames via unknown vectors involving a GSSAPI "authentication abort."...

SUSE CVE-2006-5229

OpenSSH portable 4.1 on SUSE Linux, and possibly other platforms and versions, and possibly under limited configurations, allows remote attackers to determine valid usernames via timing discrepancies in which responses take longer for valid usernames than invalid ones, as demonstrated by sshtime...

SUSE CVE-2006-5794

Unspecified vulnerability in the sshd Privilege Separation Monitor in OpenSSH before 4.5 causes weaker verification that authentication has been successful, which might allow attackers to bypass authentication. NOTE: as of 20061108, it is believed that this issue is only exploitable by leveraging...

SUSE CVE-2007-2243
