Red Hat 6.x and 7 Critical Advisory: GnuPG Key Import Issues

Updated gnupg packages are now available for Red Hat Linux 6.x and 7.. ` --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated gnupg packages now available Advisory ID: RHSA-2000:131-02 Issue date: 2000-12-19 Updated on: 2000-12-19 Product: Red Hat Linux Keywords: gnupg secret-key web-of-trust detached-signature Cross references: --------------------------------------------------------------------- 1. Topic: Updated gnupg packages are now available for Red Hat Linux 6.x and 7. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 3. Problem description: 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 check detached signatures, if the data file being checked contained clearsigned data, GnuPG would not warn the user if the detached signature was incorrect. 4. 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 6. RPMs required: Red Hat Linux 6.2: SRPMS: alpha: i386: sparc: Red Hat Linux 7.0: SRPMS: alpha: i386: 7. Verification: MD5 sum Package Name -------------------------------------------------------------------------- aae767039effc37d4a929428e0d19543 6.2/alpha/gnupg-1.0.4-8.6.x.alpha.rpm 887b2d7d888fb8ee84c81cee7832384e 6.2/i386/gnupg-1.0.4-8.6.x.i386.rpm d7a3124166bc5c35cd3ca2dec36c97e0 6.2/sparc/gnupg-1.0.4-8.6.x.sparc.rpm 1f476ae8f5453655a4a61174de187d15 7.0/alpha/gnupg-1.0.4-9.alpha.rpm 88ac7d34da177b6c469e0f2a0f6117e6 7.0/i386/gnupg-1.0.4-9.i386.rpm 5e454eb08ce03f26eccbf7007026cd56 6.2/SRPMS/gnupg-1.0.4-8.6.x.src.rpm 4e81b35255980b0884e2f1ae3cf026d5 7.0/SRPMS/gnupg-1.0.4-9.src.rpm These packages are GPG signed by Red Hat, Inc. for security.
