nodejs: DoS with keep-alive HTTP connection

Keep-alive HTTP and HTTPS connections can remain open and inactive for up to 2 minutes in Node.js 6.16.0 and earlier. Node.js 8.0.0 introduced a dedicated server.keepAliveTimeout which defaults to 5 seconds. The behavior in Node.js 6.16.0 and earlier is a potential Denial of Service (DoS) attack vector. Node.js 6.17.0 introduces server.keepAliveTimeout and the 5-second default.

nodejs: Insufficient Slowloris fix causing DoS via server.headersTimeout bypass

In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1.

runc: Execution of malicious containers allows for container escape and access to host filesystem

runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.

rubygem-actionpack: denial of service vulnerability in Action View

There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive.

An exploitable code execution vulnerability exists in the ss-manager binary of Shadowsocks-libev 3.3.2. Specially crafted network packets sent to ss-manager can cause an arbitrary binary to run, resulting in code execution and privilege escalation. An attacker can send network packets to trigger this vulnerability.

An exploitable denial-of-service vulnerability exists in the UDPRelay functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher and a local_address, arbitrary UDP packets can cause a FATAL error code path and exit. An attacker can send arbitrary UDP packets to trigger this vulnerability.

mesa: security bypass in 3D library graphics

An exploitable shared memory permissions vulnerability exists in the functionality of X11 Mesa 3D Graphics Library 19.1.2. An attacker can access the shared memory without any specific permissions to trigger this vulnerability.

An exploitable code execution vulnerability exists in the XPM image rendering function of SDL2_image 2.0.4. A specially crafted XPM image can cause an integer overflow in the colorhash function, allocating too small of a buffer. This buffer can then be written out of bounds, resulting in a heap overflow, ultimately ending in code execution. An attacker can display a specially crafted image to trigger this vulnerability.

An exploitable code execution vulnerability exists in the XPM image rendering functionality of SDL2_image 2.0.4. A specially crafted XPM image can cause an integer overflow, allocating too small of a buffer. This buffer can then be written out of bounds resulting in a heap overflow, ultimately ending in code execution. An attacker can display a specially crafted image to trigger this vulnerability.

An exploitable code execution vulnerability exists in the XCF image rendering functionality of SDL2_image 2.0.4. A specially crafted XCF image can cause a heap overflow, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.

An exploitable code execution vulnerability exists in the PCX image-rendering functionality of SDL2_image 2.0.4. A specially crafted PCX image can cause a heap overflow, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.

An exploitable integer overflow vulnerability exists when loading a PCX file in SDL2_image 2.0.4. A specially crafted file can cause an integer overflow, resulting in too little memory being allocated, which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.

An exploitable heap-based buffer overflow vulnerability exists when loading a PCX file in SDL2_image, version 2.0.4. A missing error handler can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.

Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user.
