Multiple vulnerabilities have been found in ejabberd, the worst of which allowing for remote Denial of Service.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| net-im/ejabberd | * | < 2.1.9 | >= 2.1.9 |
ejabberd is the Erlang jabber daemon.
Multiple vulnerabilities have been discovered in ejabberd. Please review the CVE identifiers referenced below for details.
ejabberd allows remote attackers to cause a Denial of Service condition with the result of either crashing the daemon or the whole system by causing memory and CPU consumption.
There is no known workaround at this time.
All ejabberd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/ejabberd-2.1.9"
An error in the usage of the ssl-cert eclass within multiple ebuilds might allow for disclosure of generated SSL private keys.

The ssl-cert eclass is a code module used by Gentoo ebuilds to generate SSL certificates.
Robin Johnson reported that the docert() function provided by ssl-cert.eclass can be called by source building stages of an ebuild, such as src_compile() or src_install(), which will result in the generated SSL keys being included inside binary packages (binpkgs).
A local attacker could recover the SSL keys from publicly readable binary packages when "emerge" is called with the "--buildpkg (-b)" or "--buildpkgonly (-B)" option. Remote attackers can recover these keys if the packages are served to a network. Binary packages built using "quickpkg" are not affected.
Do not use pre-generated SSL keys, but use keys that were generated using a different Certificate Authority.
Upgrading to newer versions of the above packages will neither remove possibly compromised SSL certificates, nor old binary packages. Please remove the certificates installed by Portage, and then emerge an upgrade to the package.
