It was discovered that libpng did not properly verify the embedded profile length of iCCP chunks. An attacker could exploit this to cause a denial of service via application crash. This issue only affected Ubuntu 8.04 LTS. (CVE-2009-5063)

Jueri Aedla discovered that libpng did not properly verify the size used when allocating memory during chunk decompression. If a user or automated system using libpng were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or execute code with the privileges of the user invoking the program. (CVE-2011-3026).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201206-15 (libpng: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libpng:
      The &ldquo;embedded_profile_len()&rdquo; function in pngwutil.c does not         check for negative values, resulting in a memory leak (CVE-2009-5063).
      The &ldquo;png_format_buffer()&rdquo; function in pngerror.c contains an         off-by-one error (CVE-2011-2501).
      The &ldquo;png_rgb_to_gray()&rdquo; function in pngrtran.c contains an         integer overflow error (CVE-2011-2690).
      The &ldquo;png_err()&rdquo; function in pngerror.c contains a NULL pointer         dereference error (CVE-2011-2691).
      The &ldquo;png_handle_sCAL()&rdquo; function in pngrutil.c improperly handles         malformed sCAL chunks(CVE-2011-2692).
      The &ldquo;png_decompress_chunk()&rdquo; function in pngrutil.c contains an         integer overflow error (CVE-2011-3026).
      The &ldquo;png_inflate()&rdquo; function in pngrutil.c contains and out of         bounds error (CVE-2011-3045).
      The &ldquo;png_set_text_2()&rdquo; function in pngset.c contains an error         which could result in memory corruption (CVE-2011-3048).
      The &ldquo;png_formatted_warning()&rdquo; function in pngerror.c contains an         off-by-one error (CVE-2011-3464).
  Impact :

    An attacker could exploit these vulnerabilities to execute arbitrary       code with the permissions of the user running the vulnerable program,       which could be the root user, or to cause programs linked against the       library to crash.
  Workaround :

    There is no known workaround at this time.
