Ubuntu Security Notice 2434-2 - USN-2434-1 fixed a vulnerability in JasPer. This update provides the corresponding fix for the JasPer library embedded in the Ghostscript package. Jose Duart discovered that JasPer incorrectly handled certain malformed JPEG-2000 image files. 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. Various other issues were also addressed.
