|2020-07-28||CVE-2020-16088|| Authorization Bypass Through User-Controlled KEY vulnerability in Openbsd |
iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches.
| 7.5 |
|2020-07-24||CVE-2020-15778|| OS Command Injection vulnerability in Openbsd Openssh |
scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument.
| 6.8 |
|2020-06-29||CVE-2020-14145|| Information Exposure vulnerability in Openbsd Openssh |
The client side in OpenSSH 5.7 through 8.3 has an Observable Discrepancy leading to an information leak in the algorithm negotiation.
| 4.3 |
|2020-06-01||CVE-2020-12062|| Improper Input Validation vulnerability in Openbsd Openssh 8.2 |
** DISPUTED ** The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server.

|2020-02-12||CVE-2011-3336|| Resource Exhaustion vulnerability in multiple products |
regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion.
| 7.8 |
|2020-01-29||CVE-2020-7247|| Unchecked Return Value vulnerability in multiple products |
smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field.
| 10.0 |
|2020-01-23||CVE-2015-5333|| Resource Exhaustion vulnerability in multiple products |
Memory leak in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (memory consumption) via a large number of ASN.1 object identifiers in X.509 certificates.
| 5.0 |
|2020-01-23||CVE-2015-5334|| Out-Of-Bounds Write vulnerability in multiple products |
Off-by-one error in the OBJ_obj2txt function in LibreSSL before 2.3.1 allows remote attackers to cause a denial of service (program crash) or possible execute arbitrary code via a crafted X.509 certificate, which triggers a stack-based buffer overflow.
| 7.5 |
|2019-12-30||CVE-2012-5663|| Incomplete Cleanup vulnerability in Openbsd Textproc/Isearch |
The isearch package (textproc/isearch) before 1.47.01nb1 uses the tempnam() function to create insecure temporary files into a publicly-writable area (/tmp).
| 5.0 |
|2019-12-12||CVE-2019-19726|| Improper Privilege Management vulnerability in Openbsd |
OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit.
| 7.2 |
