Name of the Vulnerable Software and Affected Versions RubyGems versions prior to 2.7.6

Description The issue is related to incorrect handling of the tar archive header in RubyGems, which can lead to the formation of an infinite loop. Exploitation of this issue may allow a remote attacker to cause a denial of service.

Recommendations For versions prior to 2.7.6, update to version 2.7.6 or later to resolve the issue. As a temporary workaround, consider restricting the use of the tar header processing functionality in RubyGems until a patch is available.
