"The remote host is affected by the vulnerability described in GLSA-200409-07
(xv: Buffer overflows in image handling)

    Multiple buffer overflow and integer handling vulnerabilities have been
    discovered in xv's image processing code. These vulnerabilities have been
    found in the xvbmp.c, xviris.c, xvpcx.c and xvpm.c source files.
  
Impact :

    An attacker might be able to embed malicious code into an image, which
    would lead to the execution of arbitrary code under the privileges of the
    user viewing the image.
  
Workaround :

    There is no known workaround at this time."
