| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-12-18 | CVE-2023-48795 | Improper Validation of Integrity Check Value vulnerability in multiple products The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. network high complexity openbsd putty filezilla-project microsoft panic roumenpetrov winscp bitvise lancom-systems vandyke libssh net-ssh ssh2-project proftpd freebsd crates tera-term-project oryx-embedded crushftp netsarang paramiko redhat golang russh-project sftpgo-project erlang matez libssh2 asyncssh-project dropbear-ssh-project jadaptive ssh thorntech netgate connectbot apache tinyssh trilead 9bis gentoo fedoraproject debian apple CWE-354 | 5.9 |
| 2019-12-10 | CVE-2019-14889 | OS Command Injection vulnerability in multiple products A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. | 8.8 |
| 2016-04-13 | CVE-2016-0739 | Information Exposure vulnerability in multiple products libssh before 0.7.3 improperly truncates ephemeral secrets generated for the (1) diffie-hellman-group1 and (2) diffie-hellman-group14 key exchange methods to 128 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes confusion bug." | 4.3 |
| 2016-04-13 | CVE-2015-3146 | Denial of Service vulnerability in libssh The (1) SSH_MSG_NEWKEYS and (2) SSH_MSG_KEXDH_REPLY packet handlers in package_cb.c in libssh before 0.6.5 do not properly validate state, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted SSH packet. | 5.0 |
| 2014-03-14 | CVE-2014-0017 | Cryptographic Issues vulnerability in Libssh 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. | 1.9 |
| 2013-02-05 | CVE-2013-0176 | Resource Management Errors vulnerability in Libssh 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. | 4.3 |
| 2012-11-30 | CVE-2012-6063 | Resource Management Errors vulnerability in Libssh 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. | 7.5 |
| 2012-11-30 | CVE-2012-4562 | Numeric Errors vulnerability in Libssh 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. | 7.5 |
| 2012-11-30 | CVE-2012-4561 | Buffer Overflow and Denial of Service vulnerability in libssh 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 to cause a denial of service (crash) via unspecified vectors. | 5.0 |
| 2012-11-30 | CVE-2012-4560 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in Libssh 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. | 7.5 |
