Gentoo Linux Security Advisory GLSA 200810-03 – A memory management error in libspf2 might allow for remote execution of arbitrary code. libspf2 uses a fixed-length buffer to receive DNS responses and does not properly check the length of TXT records, leading to buffer overflows. Versions less than 1.2.8 are affected.
