From ${URL} : Two flaws in RPM (actually one of them is in cpio, which is embedded into RPM) was found by Florian Weimer of Red Hat Product Security. Details as follows: CVE-2013-6435: It was found that RPM wrote file contents to the target installation directory under a temporary name, and verified its cryptographic signature only after the temporary file has been written completely. Under certain conditions, the system interprets the unverified temporary file contents and extracts commands from it. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation. Reference: https://bugzilla.redhat.com/show_bug.cgi?id=1039811 CVE-2014-8118: It was found that RPM could encounter an integer overflow, leading to a stack-based overflow, while parsing a crafted CPIO header in the payload section of an RPM file. This could allow an attacker to modify signed RPM files in such a way that they would execute code chosen by the attacker during package installation. Reference: https://bugzilla.redhat.com/show_bug.cgi?id=1168715 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
CVE-2014-8118 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-8118): Integer overflow in RPM 4.12 and earlier allows remote attackers to execute arbitrary code via a crafted CPIO header in the payload section of an RPM file, which triggers a stack-based buffer overflow. CVE-2013-6435 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-6435): Race condition in RPM 4.11.1 and earlier allows remote attackers to execute arbitrary code via a crafted RPM file whose installation extracts the contents to temporary files before validating the signature, as demonstrated by installing a file in the /etc/cron.d directory.

This really needs to get fixed. amavisd uses rpm2cpio when scanning mail. It's not inconceivable that a specially crafted attachment could be used to compromise a mail server running amavisd.
Updated rpm ebuilds are available in the junkdrawer overlay.
@maintainers ping Please bump to app-arch/rpm-4.13.0. Michael Boyle Gentoo Security Padawan
alpha, amd64, arm, arm64, ia64, ppc, ppc64, x86: please test and mark stable =app-arch/rpm-4.14.1
amd64 stable
>>> Test phase: app-arch/rpm-4.14.1 * Test::Harness Jobs=99 make -j99 test TEST_VERBOSE=0 make: *** No rule to make target 'test'. Stop. * ERROR: app-arch/rpm-4.14.1::gentoo failed (test phase): * emake failed
Hum, I'm sure I did run the 'test' phase on that package when writing this ebuild at some point. But I indeed get the same error, so something broke along the way. Oops, sorry, will fix soon.
I reverted amd64's stabilization. Looks like the package has serious test failures, see bug 657500. Note: Tests in previous ebuilds were disabled/missing. I wouldn't block stabilization if tests wouldn't fail with > Failed to initialize NSS library message which looks like a major incompatibility with NSS/NSPR, see https://access.redhat.com/solutions/3134931.
Bug 657500 has been resolved, so here I go again: alpha, amd64, arm, arm64, ia64, ppc, ppc64, x86: please test and mark stable =app-arch/rpm-4.14.1

Reluctantly stable on arm64 due to test failures, but this is for security + earlier versions didn't run tests afaik..
