USN-5298-1: Linux kernel vulnerabilities

It was discovered that the Packet network protocol implementation in the Linux kernel contained a double-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2021-22600 Jürgen Groß discovered that the Xen subsystem...

kernel: use-after-free in RDMA listen()

A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this...

FreeBSD : seatd-launch -- remove files with escalated privileges with SUID (1cd565da-455e-41b7-a5b9-86ad8e81e33e)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 1cd565da-455e-41b7-a5b9-86ad8e81e33e advisory. - Kenny Levinsen reports: seatd-launch could use a user-specified socket path instead of the internally...

ruby: BasicSocket#read_nonblock method leads to information disclosure

An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocketreadnonblockrequestedsize, buffer, exception: false, the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous valu...

seatd-launch -- remove files with escalated privileges with SUID

Kenny Levinsen reports: seatd-launch could use a user-specified socket path instead of the internally generated socket path, and would unlink the socket path before use to guard against collision with leftover sockets. This meant that a caller could freely control what file path would be unlinked...
