multiple vulnerabilities :

  - An error exists within the 'cli_pdf()' function in

  - An error exists within the 'parseicon()' function in
    'libclamav/pe_icons.c' when processing PE icons.  This
    can be exploited to trigger an out-of-bounds access when
    reading data and potentially cause a crash via a
    specially crafted PE file. (Bug 2031)");
