qemu: DoS via large option request

The Network Block Device NBD server in Quick Emulator QEMU, is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other...

kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe systemwide activity

The netlinkdelivertapskb function in net/netlink/afnetlink.c in the Linux kernel, through 4.14.4, does not restrict observations of Netlink messages to a single net namespace, when CONFIGNLMON is enabled. This allows local users to obtain sensitive information by leveraging the CAPNETADMIN...

FreeBSD Denial of Service Vulnerability (CNVD-2018-07703)

FreeBSD is a set of Unix-like free operating systems in the FreeBSD project, headed by the Core Team team, and is an important branch of Unix-like systems that have evolved through BSD, 386BSD, and 4.4BSD. A security vulnerability exists in FreeBSD that stems from the length field of the ipsec...

CVE-2018-6918

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, the length field of the ipsec option header does not count the size of the option header itself, causing an infinite loop when the length is zero. This issue can allow a remote attacker who is able ...

CVE-2018-6918

Removed by vendor...

The vulnerability of the “go get” command implementation in the Go programming language allows a perpetrator to execute arbitrary commands.

The vulnerability of the “go get” command in the Go programming language exists due to insufficient validation of input data insufficient checking of the import path when using the “-insecure” option. Exploiting this vulnerability allows a malicious actor to execute arbitrary commands using a...

FreeBSD -- ipsec crash or denial of service

Problem Description: The length field of the option header does not count the size of the option header itself. This causes a problem when the length is zero, the count is then incremented by zero, which causes an infinite loop. In addition there are pointer/offset mistakes in the handling of IPv...
