Red Hat: two 'gnupg' vulnerabilities
Summary
Summary
When importing keys from public key servers, GnuPG will import private keys(also known as secret keys) in addition to public keys. If this happens,the user's web of trust becomes corrupted. Additionally, when used to checkdetached signatures, if the data file being checked contained clearsigneddata, GnuPG would not warn the user if the detached signature wasincorrect.
Solution
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed ( for more info):
21889 - Web of trust circumvention by secret key distribution
21498 - Detached signature verification vulnerability

You can verify each package with the following command:
rpm --checksig
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg
