Summary

Insight
Insight
Multiple vulnerabilities was found and corrected in libtiff: Heap-based buffer overflow in tif_pixarlog.c in LibTIFF before 4.0.3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted TIFF image using the PixarLog Compression format (CVE-2012-4447). ppm2tiff does not check the return value of the TIFFScanlineSize function, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PPM image that triggers an integer overflow, a zero-memory allocation, and a heap-based buffer overflow (CVE-2012-4564). The updated packages have been patched to correct these issues.
