|---|---|---|---|
| 2020-01-29 | CVE-2020-7247 | Improper Handling of Exceptional Conditions 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. | 9.8 |
| 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. | 7.5 |
| 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. | 9.8 |
| 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). | 7.5 |
| 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. | 7.8 |
| 2019-12-11 | CVE-2019-14899 | A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. | 7.4 |
| 2019-12-10 | CVE-2012-1577 | Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) vulnerability in multiple products lib/libc/stdlib/random.c in OpenBSD returns 0 when seeded with 0. | 9.8 |
| 2019-12-05 | CVE-2019-19522 | Incorrect Permission Assignment for Critical Resource vulnerability in Openbsd 6.6 OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. | 7.8 |
| 2019-12-05 | CVE-2019-19521 | Improper Authentication vulnerability in Openbsd 6.6 libc in OpenBSD 6.6 allows authentication bypass via the -schallenge username, as demonstrated by smtpd, ldapd, or radiusd. | 9.8 |
| 2019-12-05 | CVE-2019-19520 | Incorrect Authorization vulnerability in Openbsd 6.6 xlock in OpenBSD 6.6 allows local users to gain the privileges of the auth group by providing a LIBGL_DRIVERS_PATH environment variable, because xenocara/lib/mesa/src/loader/loader.c mishandles dlopen. | 7.8 |
