A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

  • CVE-2022-23521: A flaw was found in Git, a distributed revision control system. When parsing gitattributes, a mechanism to allow defining attributes for paths, multiple integer overflows can occur when there is a huge number of path patterns, attributes for a single pattern, or declared attribute names. These overflows can be triggered via a crafted .gitattributes file that may be part of the commit history. Git silently splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index, or both. This integer overflow can result in arbitrary heap reads and writes, which may allow remote code execution.
  • CVE-2022-41903: A flaw was found in Git, a distributed revision control system. This issue occurs due to an integer overflow in pretty.c::format_and_pad_commit(), where asize_tis stored improperly as anint, and then added as an offset to amemcpy(). This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g.,git log --format=…`). It may also be triggered indirectly through the git archive via the export-subst mechanism, which expands format specifiers inside files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may allow arbitrary code execution.

Topic

An update for git is now available for Red Hat Enterprise Linux 8.1 Update Services for SAP Solutions.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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.

Security Fix(es):

  • git: gitattributes parsing integer overflow (CVE-2022-23521)
  • git: Heap overflow in `git archive`, `git log --format` leading to RCE (CVE-2022-41903)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat Security Advisory 2023-0609-01

Red Hat Security Advisory 2023-0609-01 - 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 heap overflow and integer overflow vulnerabilities.

Git Users Urged to Update Software to Prevent Remote Code Execution Attacks

The maintainers of the Git source code version control system have released updates to remediate two critical vulnerabilities that could be exploited by a malicious actor to achieve remote code execution. The flaws, tracked as CVE-2022-23521 and CVE-2022-41903, impacts the following versions of Git: v2.30.6, v2.31.5, v2.32.4, v2.33.5, v2.34.5, v2.35.5, v2.36.3, v2.37.4, v2.38.2, and v2.39.0.

CVE-2022-41903: Heap overflow in `git archive`, `git log --format` leading to RCE

Git is distributed revision control system. `git log` can display commits in an arbitrary format using its `--format` specifiers. This functionality is also exposed to `git archive` via the `export-subst` gitattribute. When processing the padding operators, there is a integer overflow in `pretty.c::format_and_pad_commit()` where a `size_t` is stored improperly as an `int`, and then added as an offset to a `memcpy()`. This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., `git log --format=...`). It may also be triggered indirectly through git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may result in arbitrary code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. Users who are unable to u...

CVE-2022-23521: gitattributes parsing integer overflow

Git is distributed revision control system. gitattributes are a mechanism to allow defining attributes for paths. These attributes can be defined by adding a `.gitattributes` file to the repository, which contains a set of file patterns and the attributes that should be set for paths matching this pattern. When parsing gitattributes, multiple integer overflows can occur when there is a huge number of path patterns, a huge number of attributes for a single pattern, or when the declared attribute names are huge. These overflows can be triggered via a crafted `.gitattributes` file that may be part of the commit history. Git silently splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index or both. This integer overflow can result in arbitrary heap reads and writes, which may result in remote code execution. The problem has been patched i...
