CVE-2017-7525 [CRITICAL] CWE-184 CVE-2017-7525: A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.

CVE-2019-11479 [HIGH] CWE-405 CVE-2019-11479: Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, a

CVE-2018-8088 [CRITICAL] CVE-2018-8088: org.slf4j.ext.EventData in the slf4j-ext module in QOS.CH SLF4J before 1.8.0-beta2 allows remote att 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-2018-1120 [MEDIUM] CWE-122 CVE-2018-1120: A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file ont A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc//cmdline (or /proc//environ) files to blo
