"The remote host is affected by the vulnerability described in GLSA-200501-07
(xine-lib: Multiple overflows)

    Ariel Berkman discovered that xine-lib reads specific input data
    into an array without checking the input size in demux_aiff.c, making
    it vulnerable to a buffer overflow (CAN-2004-1300) . iDefense
    discovered that the PNA_TAG handling code in pnm_get_chunk() does not
    check if the input size is larger than the buffer size (CAN-2004-1187).
    iDefense also discovered that in this same function, a negative value
    could be given to an unsigned variable that specifies the read length
    of input data (CAN-2004-1188).
  
Impact :

    A remote attacker could craft a malicious movie or convince a
    targeted user to connect to a malicious PNM server, which could result
    in the execution of arbitrary code with the rights of the user running
    any xine-lib frontend.
  
Workaround :

    There is no known workaround at this time."
