Description GLSAMaker/CVETool Bot gentoo-dev 2017-12-04 01:54:32 UTC
CVE-2017-17095 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-17095):
  tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to cause
  a denial of service (TIFFSetupStrips heap-based buffer overflow and
  application crash) or possibly have unspecified other impact via a crafted
  TIFF file.

I guess it happens also on a stable version
Comment 2 SpanKY gentoo-dev 2018-01-26 03:37:29 UTC
i think this is:
  http://bugzilla.maptools.org/show_bug.cgi?id=2750

a mitigation was added for the next release, but i don't think it fixes it fully:
