Red Hat Security Advisory 2020-1975-01 - Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Issues addressed include a password leak vulnerability.

FreeBSD Security Advisory - While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service. An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.

FreeBSD Security Advisory - With certain inputs, iconv may write beyond the end of the output buffer. Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.

FreeBSD Security Advisory - To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device. A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.
