On Vsyscalls and the VDSO

  (2011) Anyway, I like this sentence a lot: > One useful point from that discussion is that the static vsyscall page is not, in fact, a security vulnerability; it's simply a resource which can make it easier for an attacker to exploit a vulnerability elsewhere in the system. One thing that's always irritated me is that dubious "hardening" changes like this one get lumped together with fixes for actual vulnerabilities, and then both get labeled as "security".
