    t1lib 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
    
    Summary:
    
    t1lib could be made to crash or run programs as your login if it opened a
    specially crafted font file.
    
    Software Description:
    - t1lib: Type 1 font rasterizer library - runtime
    
    Details:
    
    Jon Larimer discovered that t1lib did not properly parse AFM fonts. If a
    user were tricked into using a specially crafted font file, a remote
    attacker could cause t1lib to crash or possibly execute arbitrary code with
    user privileges. (CVE-2010-2642, CVE-2011-0433)
    
    Jonathan Brossard discovered that t1lib did not correctly handle certain
    malformed font files. If a user were tricked into using a specially crafted
    font file, a remote attacker could cause t1lib to crash. (CVE-2011-1552,
    CVE-2011-1553, CVE-2011-1554)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      libt1-5                         5.1.2-3ubuntu0.11.10.2
    
    Ubuntu 11.04:
      libt1-5                         5.1.2-3ubuntu0.11.04.2
    
    Ubuntu 10.10:
      libt1-5                         5.1.2-3ubuntu0.10.10.2
    
    Ubuntu 10.04 LTS:
      libt1-5                         5.1.2-3ubuntu0.10.04.2
    
    In general, a standard system update will make all the necessary changes.
