AlquistManager branch as of commit 280d99f43b11378212652e75f6f3159cde9c1d36 is affected by a directory traversal vulnerability. This attack can cause the disclosure of critical secrets stored anywhere on the system andcan significantly aid in getting remote code access.

Clustering master branch as of commit 53e663e259bcfc8cdecb56c0bb255bd70bfcaa70 is affected by a directory traversal vulnerability. This attack can cause the disclosure of critical secrets stored anywhere on the system and can significantly aid in getting remote code access.

The Keybase Client for Windows before version 5.7.0 contains a path traversal vulnerability when checking the name of a file uploaded to a team folder. A malicious user could upload a file to a shared folder with a specially crafted file name which could allow a user to execute an application which was not intended on their host machine. If a malicious user leveraged this issue with the public folder sharing feature of the Keybase client, this could lead to remote code execution.

pdf2xml v2.0 was discovered to contain a heap-buffer overflow in the function TextPage::addAttributsNode.

Ubuntu Security Notice 5134-1 - An information disclosure issue was discovered in the command line interface of Docker. A misconfigured credential store could result in supplied credentials being leaked to the public registry, when using the docker login command with a private registry.

Ubuntu Security Notice 5137-1 - It was discovered that the f2fs file system in the Linux kernel did not properly validate metadata in some situations. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service or possibly execute arbitrary code. It was discovered that the Infiniband RDMA userspace connection manager implementation in the Linux kernel contained a race condition leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possible execute arbitrary code. Various other issues were also addressed.

Ubuntu Security Notice 5136-1 - It was discovered that the f2fs file system in the Linux kernel did not properly validate metadata in some situations. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service or possibly execute arbitrary code. It was discovered that the FUSE user space file system implementation in the Linux kernel did not properly handle bad inodes in some situations. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice 5135-1 - It was discovered that the Linux kernel did not properly account for the memory usage of certain IPC objects. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5130-1 - Jann Horn discovered a race condition in the tty subsystem of the Linux kernel in the locking for the TIOCSPGRP ioctl, leading to a use-after- free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Jann Horn discovered that the tty subsystem of the Linux kernel did not use consistent locking in some situations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly expose sensitive information. Various other issues were also addressed.

Ubuntu Security Notice 5133-1 - It was discovered that ICU contains a use after free issue. An attacker could use this issue to cause a denial of service with crafted input.
