DESCRIPTION:
Some vulnerabilities have been reported in CUPS, which potentially
can be exploited by malicious people to compromise a vulnerable
system.

1) Two boundary errors exist in the implementation of the HP-GL/2
filter. These can be exploited to cause buffer overflows via HP-GL/2
files containing overly large pen numbers.

2) A boundary error exists within the "read_rle16()" function when
processing SGI (Silicon Graphics Image) files. This can be exploited
to cause a heap-based buffer overflow via a specially crafted SGI
file.

3) An integer overflow error exists within the "WriteProlog()"
function included in the "texttops" utility. This can be exploited to
cause a heap-based buffer overflow via a specially crafted file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

The vulnerabilities are reported in versions prior to 1.3.9.

SOLUTION:
Update to version 1.3.9.
