3c4a3a5cf1e480feed4b9092b1aa939f9e0eaf1cd0b6da12b95876f269e7e405Red Hat Security Advisory 2015-0698-01 - Red Hat Enterprise Virtualization Manager provides access to virtual machines using SPICE. These SPICE client packages provide the SPICE client and usbclerk service for both Windows 32-bit operating systems and Windows 64-bit operating systems. This update adds support for the TLS Fallback Signaling Cipher Suite Value, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails.

0cb97b8a4ed08246139031846f5ec96c37efe43c2bb067741bc0ba578c6a9e81Ubuntu Security Notice 1317-1 - It was discovered that Ghostscript did not correctly handle memory allocation when parsing certain malformed JPEG-2000 images. If a user or automated system were tricked into opening a specially crafted image, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. It was discovered that Ghostscript did not correctly handle certain formatting operations when parsing JPEG-2000 images. If a user or automated system were tricked into opening a specially crafted image, an attacker could cause a denial of service and possibly execute arbitrary code with user privileges. Various other issues were also addressed.

If a user were tricked into opening a specially crafted JPEG-2000 image file, a remote attacker could cause JasPer to crash or possibly execute arbitrary code with user privileges.
c582938b1c84e55bad817ace630c8366e6860f089002b1d34130292263c8abc6Mandriva Linux Security Advisory 2011-189 - Heap-based buffer overflow in the jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c in JasPer 1.900.1 allows remote attackers to execute arbitrary code or cause a denial of service via a crafted numrlvls value in a JPEG2000 file. The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c in JasPer 1.900.1 uses an incorrect data type during a certain size calculation, which allows remote attackers to trigger a heap-based buffer overflow and execute arbitrary code, or cause a denial of service (heap memory corruption), via a malformed JPEG2000 file. The updated packages have been patched to correct these issues.
46af9b534c46d06cfd6da996d0cfe4b3b0a15d7995cbf4be5b4cffcac8d5d385Red Hat Security Advisory 2011-1811-01 - The netpbm packages contain a library of functions which support programs for handling various graphics file formats, including .pbm, .pgm, .pnm, .ppm, and others. Two heap-based buffer overflow flaws were found in the embedded JasPer library, which is used to provide support for Part 1 of the JPEG 2000 image compression standard in the jpeg2ktopam and pamtojpeg2k tools. An attacker could create a malicious JPEG 2000 compressed image file that could cause jpeg2ktopam to crash or, potentially, execute arbitrary code with the privileges of the user running jpeg2ktopam. These flaws do not affect pamtojpeg2k.
4e30cdb614403f06bdbc810bb652c4ffc82fcffc0b429f074d8a9abad1cea938Red Hat Security Advisory 2011-1807-01 - JasPer is an implementation of Part 1 of the JPEG 2000 image compression standard. Two heap-based buffer overflow flaws were found in the way JasPer decoded JPEG 2000 compressed image files. An attacker could create a malicious JPEG 2000 compressed image file that, when opened, would cause applications that use JasPer to crash or, potentially, execute arbitrary code.
