详细描述

git: The git dæmon for supporting git:// access to git repositories
shim: This package provides debug information for package shim. Debug information is useful when developing applications that use this package or when debugging this package.


Security Fix(es):
git: A flaw was found in git where credentials can be leaked through the use of a crafted URL. The crafted URL must contain a newline, empty host, or lack a scheme so that the credential helper is fulled into giving the information of a different host to the client. The highest threat from this vulnerability is to data confidentiality.(CVE-2020-11008)
git: bugfix
shim: A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-10713)
shim: bugfix
