CVE-2021-3753

Status Candidate

Overview

A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.

Ubuntu Security Notice 6221-1 - It was discovered that a race condition existed in the overlay file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service. It was discovered that the virtual terminal device implementation in the Linux kernel contained a race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 6037-1 - ZeddYu Lu discovered that the FTP client from Apache Commons Net trusted the host from PASV responses by default. A remote attacker with a malicious FTP server could redirect the client to another server, which could possibly result in leaked information about services running on the private network of the client.

Debian Linux Security Advisory 5307-1 - ZeddYu Lu discovered that the FTP client of Apache Commons Net, a Java client API for basic Internet protocols, trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client.

Ubuntu Security Notice 5137-2 - 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.
