CVE-2012-6088 low priority: Ubuntu including 1 source packages (rpm), 6 status rows across 6 suites (hardy, lucid, oneiric, precise, quantal, upstream): not-affected 3, released 2, ignored 1.
The rpmpkgRead function in lib/package.c in RPM 4.10.x before 4.10.2 does not return an error code in certain situations involving an "unparseable signature," which allows remote attackers to bypass RPM signature checks via a crafted package.
