CVE-2012-0061: Input Validation
It was discovered that RPM did not properly validate region size in headerLoad() when loading header from an RPM file, allowing region size to exceed containing header size. A malformed or malicious RPM file could cause RPM to crash and possibly execute arbitrary code before file signature was properly verified.

Other sources
The headerLoad function in lib/header.c in RPM before 4.9.1.3 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.
