Name of the Vulnerable Software and Affected Versions libsolv versions through 0.7.2

Description The issue is related to errors in resource management, specifically in the pool whatprovides function of the libsolv library. It may allow a remote attacker to cause a denial of service. However, it is noted that the issue may only affect the test suite and not the underlying library, and it cannot be exploited in any real-world application.

Recommendations For libsolv versions through 0.7.2, consider updating to a version where this issue is resolved, if such a version exists. At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the pool whatprovides function until a patch is available.
