    php5 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    Several security issues were fixed in PHP.
    
    Software Description:
    - php5: HTML-embedded scripting language interpreter
    
    Details:
    
    It was discovered that PHP incorrectly handled certain Tidy::diagnose
    operations on invalid objects. A remote attacker could use this flaw to
    cause PHP to crash, leading to a denial of service. (CVE-2012-0781)
    
    It was discovered that PHP incorrectly handled certain multi-file upload
    filenames. A remote attacker could use this flaw to cause a denial of
    service, or to perform a directory traversal attack. (CVE-2012-1172)
    
    Rubin Xu and Joseph Bonneau discovered that PHP incorrectly handled certain
    Unicode characters in passwords passed to the crypt() function. A remote
    attacker could possibly use this flaw to bypass authentication.
    (CVE-2012-2143)
    
    It was discovered that a Debian/Ubuntu specific patch caused PHP to
    incorrectly handle empty salt strings. A remote attacker could possibly use
    this flaw to bypass authentication. This issue only affected Ubuntu 10.04
    LTS and Ubuntu 11.04. (CVE-2012-2317)
    
    It was discovered that PHP, when used as a stand alone CGI processor
    for the Apache Web Server, did not properly parse and filter query
    strings. This could allow a remote attacker to execute arbitrary code
    running with the privilege of the web server, or to perform a denial of
    service. Configurations using mod_php5 and FastCGI were not vulnerable.
    (CVE-2012-2335, CVE-2012-2336)
    
    Alexander Gavrun discovered that the PHP Phar extension incorrectly handled
    certain malformed TAR files. A remote attacker could use this flaw to
    perform a denial of service, or possibly execute arbitrary code.
    (CVE-2012-2386)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      php5                            5.3.10-1ubuntu3.2
    
    Ubuntu 11.10:
      php5                            5.3.6-13ubuntu3.8
    
    Ubuntu 11.04:
      php5                            5.3.5-1ubuntu7.10
    
    Ubuntu 10.04 LTS:
      php5                            5.3.2-1ubuntu4.17
    
    Ubuntu 8.04 LTS:
      php5                            5.2.4-2ubuntu5.25
    
    In general, a standard system update will make all the necessary changes.
