A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Red Hat RPM Package Manager It has been rated as critical. This issue affects the function headerLoad in the library lib/header.c of the component Header Region Size Handler. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The headerLoad function in lib/header.c in RPM before does not properly validate region tags, which allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large region size in a package header.
