1 CVE-2014-0017 310 +Info 2014-03-14 2014-03-26
1.9
None Local Medium Not required Partial None None
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.
2 CVE-2013-0176 399 DoS 2013-02-05 2013-02-07
4.3
None Remote Medium Not required None None Partial
The publickey_from_privatekey function in libssh before 0.5.4, when no algorithm is matched during negotiations, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a "Client: Diffie-Hellman Key Exchange Init" packet.
3 CVE-2012-6063 399 DoS Exec Code 2012-11-30 2012-12-19
7.5
None Remote Low Not required Partial Partial Partial
Double free vulnerability in the sftp_mkdir function in sftp.c in libssh before 0.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors, a different vector than CVE-2012-4559.
4 CVE-2012-4562 189 DoS Exec Code Overflow 2012-11-30 2013-08-26
7.5
None Remote Low Not required Partial Partial Partial
Multiple integer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (infinite loop or crash) and possibly execute arbitrary code via unspecified vectors, which triggers a buffer overflow, infinite loop, or possibly some other unspecified vulnerabilities.
5 CVE-2012-4561 DoS 2012-11-30 2013-08-26
5.0
None Remote Low Not required None None Partial
The (1) publickey_make_dss, (2) publickey_make_rsa, (3) signature_from_string, (4) ssh_do_sign, and (5) ssh_sign_session_id functions in keys.c in libssh before 0.5.3 free "an invalid pointer on an error path," which might allow remote attackers cause a denial of service (crash) via unspecified vectors.
6 CVE-2012-4560 119 DoS Exec Code Overflow 2012-11-30 2013-08-26
7.5
None Remote Low Not required Partial Partial Partial
Multiple buffer overflows in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors.
7 CVE-2012-4559 399 DoS Exec Code 2012-11-30 2013-08-26
6.8
None Remote Medium Not required Partial Partial Partial
Multiple double free vulnerabilities in the (1) agent_sign_data function in agent.c, (2) channel_request function in channels.c, (3) ssh_userauth_pubkey function in auth.c, (4) sftp_parse_attr_3 function in sftp.c, and (5) try_publickey_from_file function in keyfiles.c in libssh before 0.5.3 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
