SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities were found in graphicsmagick.
The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.
Off-by-one error in the DrawImage function in magick/render.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (DrawDashPolygon heap-based buffer over-read and application crash) via a crafted file.
ReadPNMImage in coders/pnm.c in GraphicsMagick 1.3.26 does not ensure the correct number of colors for the XV 332 format, leading to a NULL pointer Dereference.
ReadRLEImage in coders/rle.c in GraphicsMagick 1.3.26 mishandles RLE headers that specify too few colors, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file.
ReadDCMImage in coders/dcm.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted DICOM image, related to the ability of DCM_ReadNonNativeImages to yield an image list with zero frames.
GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (excessive memory allocation) because of an integer underflow in ReadPICTImage in coders/pict.c.
In ReadOneJNGImage in coders/png.c in GraphicsMagick 1.3.26, a NULL pointer Dereference occurs while transferring JPEG scanlines, related to a PixelPacket pointer.
For Debian 7 'Wheezy', CVE-2017-15930 has been fixed in version 1.3.16-1.1+deb7u12. The other security issues were fixed in 1.3.16-1.1+deb7u10 on 10 Oct 2017 in DLA-1130-1 but that announcement was never sent out so this advisory also contains the notice about those vulnerabilities.
We recommend that you upgrade your graphicsmagick packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
