Vulnerability from github – Published: 2022-05-24 16:55 – Updated: 2023-03-24 18:30Prior to 0.1, all builds of Eclipse OMR contain a bug where the loop versioner may fail to privatize a value that is pulled out of the loop by versioning - for example if there is a condition that is moved out of the loop that reads a field we may not privatize the value of that field in the modified copy of the loop allowing the test to see one value of the field and subsequently the loop to see a modified field value without retesting the condition moved out of the loop. This can lead to a variety of different issues but read out of array bounds is one major consequence of these problems.

GHSA-C82R-C9F7-F5MJ
Vulnerability from github – Published: 2025-04-28 20:25 – Updated: 2025-04-29 13:10Issue
Snowflake discovered and remediated a vulnerability in the Snowflake Connector for .NET (“Connector”). When using the Easy Logging feature on Linux and macOS, the Connector didn’t correctly verify the permissions of the logging configuration file, potentially allowing an attacker with local access to overwrite the configuration and gain control over logging level and output location.
This vulnerability affects Connector versions 2.1.2 through 4.4.0. Snowflake fixed the issue in version 4.4.1.
Vulnerability Details
When using the Easy Logging feature on Linux and macOS, the Connector reads logging configuration from a user-provided file. On Linux and macOS, the Connector verifies that the configuration file can be written to only by its owner. That check was vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition and failed to verify that the file owner matches the user running the Connector. This could allow a local attacker with write access to the configuration file or the directory containing it to overwrite the configuration and gain control over logging level and output location.
Solution
Snowflake released version 4.4.1 of the Snowflake Connector for .NET, which fixes this issue. We recommend users upgrade to version 4.4.1.
Additional Information
If you discover a security vulnerability in one of our products or websites, please report the issue to Snowflake through our Vulnerability Disclosure Program hosted at HackerOne. For more information, please see our Vulnerability Disclosure Policy.

Mitigation
The most basic advice for TOCTOU vulnerabilities is to not perform a check before the use. This does not resolve the underlying issue of the execution of a function on a resource whose state and identity cannot be assured, but it does help to limit the false sense of security given by the check.
Mitigation
When the file being altered is owned by the current user and group, set the effective gid and uid to that of the current user and group when executing this statement.
Mitigation
Limit the interleaving of operations on files from multiple processes.
Mitigation
If you cannot perform operations atomically and you must share access to the resource between multiple processes or threads, then try to limit the amount of time (CPU cycles) between the check and use of the resource. This will not fix the problem, but it could make it more difficult for an attack to succeed.
Mitigation
Recheck the resource after the use call to verify that the action was taken appropriately.
Mitigation
Ensure that some environmental locking mechanism can be used to protect resources effectively.
Mitigation
Ensure that locking occurs before the check, as opposed to afterwards, such that the resource, as checked, is the same as it is when in use.
CAPEC-27: Leveraging Race Conditions via Symbolic Links
This attack leverages the use of symbolic links (Symlinks) in order to write to sensitive files. An attacker can create a Symlink link to a target file not otherwise accessible to them. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file they will be writing to the sensitive file by using the Symlink. The race occurs because the system checks if the temporary file exists, then creates the file. The attacker would typically create the Symlink during the interval between the check and the creation of the temporary file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
