Gentoo : Security Vulnerabilities, CVEs, Published In 2014

Integer overflow in the tr_bitfieldEnsureNthBitAlloced function in bitfield.c in Transmission before 2.84 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted peer message, which triggers an out-of-bounds write.

The Gentoo Nullmailer package before 1.11-r2 uses world-readable permissions for /etc/nullmailer/remotes, which allows local users to obtain SMTP authentication credentials by reading the file.

The urlopen function in pym/portage/util/_urlopen.py in Gentoo Portage 2.1.12, when using HTTPS, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and modify binary package lists via a crafted certificate.
