Gentoo Linux docert() SSL key weak security
| gentoo-docert-sslkey-weak-security (41336) |  Low Risk |
Description:
Gentoo Linux could provide weaker than expected security during the source building stages of an ebuild. SSL keys are stored inside publicly readable binary packages when the docert() function is used by src_compile() or src_install(). A local attacker could exploit this vulnerability to obtain SSL keys via extraction from the binary package.

- CVE-2008-1383: The docert function in ssl-cert.eclass, when used by src_compile or src_install on Gentoo Linux, stores the SSL key in a binpkg, which allows local users to extract the key from the binpkg, and causes multiple systems that use this binpkg to have the same SSL key and certificate.
