Subject: Re: CVE Request: two flaws in hesiod permitting privilege elevation

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

> [] Weak SUID check allowing privilege elevation
> 
> Hesiod unsafely checks EUID vs UID in a few places, consulting
> environment variables for configuration if they match. This could be
> used for privilege elevation under some circumstances. The fix uses
> secure_getenv() in place of getenv().

Use CVE-2016-10151.


> [] Use of hard-coded DNS domain if configuration file cannot be read
> 
> If opening the configuration file fails, hesiod falls back on a default
> domain ".athena.mit.edu" to retrieve managed information. A local
> attacker with the opportunity to poison DNS cache could potentially
> elevate their privileges to root by causing fopen() to fail.

> https://github.com/achernya/hesiod/pull/10

Use CVE-2016-10152.
