-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Small data analysis based on August/September GLSAs :

55 GLSAs
21 of which are buffer overflows (38%)
5  are buffer overflows affecting daemons (9%)
14 are buffer overflows affecting client software (25%)
2  can potentially affect both servers and clients (4%)

So almost one third of our current vulnerabilities are buffer overflows
affecting client software. These require the attacker to make you
load/read/open a malicious document/image/playlist. It's not because we
haven't seen much viruses for Linux that we shouldn't worry about this
attack vector. Restricting ssp to daemons and +s programs is not very
useful. A client-based vulnerability can be used together with a recent
root escalation kernel vuln to compromise a machine completely. Weakest
link.
