Description Stefan Behte (RETIRED) gentoo-dev Security 2010-09-03 21:32:55 UTC
CVE-2010-2546 (
  Multiple heap-based buffer overflows in loaders/load_it.c in
  libmikmod, possibly 3.1.12, might allow remote attackers to execute
  arbitrary code via (1) crafted samples or (2) crafted instrument
  definitions in an Impulse Tracker file, related to panpts, pitpts,
  and IT_ProcessEnvelope.  NOTE: some of these details are obtained
  from third party information.  NOTE: this vulnerability exists
  because of an incomplete fix for CVE-2009-3995.
Comment 1 Stefan Behte (RETIRED) gentoo-dev Security 2010-09-03 22:30:33 UTC
CVE-2010-2971 (
  loaders/load_it.c in libmikmod, possibly 3.1.12, does not properly
  account for the larger size of name##env relative to name##tick and
  name##node, which allows remote attackers to trigger a buffer
  over-read and possibly have unspecified other impact via a crafted
  Impulse Tracker file, a related issue to CVE-2010-2546.  NOTE: this
  issue exists because of an incomplete fix for CVE-2009-3995.

Pushed fix for this CVEs (and closely related CVEs) for both stable slots:

Arches, please test and mark stable:
Target keywords : "amd64 x86"

Target keywords : "alpha amd64 arm hppa ia64 ppc ppc64 sh sparc x86"

Does this reflect the desired or expected outcome???

Both build ok with USE raw.  Otherwise amd64 looks ok
Comment 5 Maurizio Camisaschi (amd64 AT) 2012-02-07 11:38:26 UTC
just the problem with the static-libs (bug 402499)

for everything else both versions amd64 is ok
