CVE-2018-8088 3 Oracle, Qos, Redhat 14 Goldengate Application Adapters, Goldengate Stream Analytics, Utilities Framework and 11 more 2023-12-27 7.5 HIGH 9.8 CRITICAL
org.slf4j.ext.EventData in the slf4j-ext module in QOS.CH SLF4J before 1.8.0-beta2 allows remote attackers to bypass intended access restrictions via crafted data. EventData in the slf4j-ext module in QOS.CH SLF4J, has been fixed in SLF4J versions 1.7.26 later and in the 2.0.x series.
CVE-2021-3634 6 Debian, Fedoraproject, Libssh and 3 more 7 Debian Linux, Fedora, Libssh and 4 more 2023-12-22 4.0 MEDIUM 6.5 MEDIUM
A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange.
CVE-2019-14835 8 Canonical, Debian, Fedoraproject and 5 more 44 Ubuntu Linux, Debian Linux, Fedora and 41 more 2023-12-15 7.2 HIGH 7.8 HIGH
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 27 Fedora, Lldpd, Openvswitch and 24 more 2023-11-26 7.1 HIGH 7.5 HIGH
