Debian Linux Security Advisory 5540-1 - Two remotely exploitable security vulnerabilities were discovered in Jetty 9, a Java based web server and servlet engine. The HTTP/2 protocol implementation did not sufficiently verify if HPACK header values exceed their size limit. Furthermore the HTTP/2 protocol allowed a denial of service (server resource consumption) because request cancellation can reset many streams quickly. This problem is also known as Rapid Reset Attack.

Ubuntu Security Notice 6454-2 - Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service. Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of- bounds write vulnerability. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6441-3 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service or possibly execute arbitrary code.

Debian Linux Security Advisory 5539-1 - It was reported that incorrect bound checks in the dsaVerify function in node-browserify-sign, a Node.js library which adds crypto signing for browsers, allows an attacker to perform signature forgery attacks by constructing signatures that can be successfully verified by any public key.

Ubuntu Security Notice 6458-1 - It was discovered that Slurm did not properly handle credential management, which could allow an unprivileged user to impersonate the SlurmUser account. An attacker could possibly use this issue to execute arbitrary code as the root user. It was discovered that Slurm did not properly handle access control when dealing with RPC traffic through PMI2 and PMIx, which could allow an unprivileged user to send data to an arbitrary unix socket in the host. An attacker could possibly use this issue to execute arbitrary code as the root user.
