jasper vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 11.10
  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS


JasPer could be made to crash or run programs as your login if it opened a specially crafted file.

Software Description

  • jasper - Library for manipulating JPEG-2000 files


Jonathan Foote 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.
