The remote host is affected by the vulnerability described in GLSA-200710-11
(X Font Server: Multiple Vulnerabilities)
iDefense reported that the xfs init script does not correctly handle a
race condition when setting permissions of a temporary file
(CVE-2007-3103). Sean Larsson discovered an integer overflow
vulnerability in the build_range() function possibly leading to a
heap-based buffer overflow when handling 'QueryXBitmaps' and
'QueryXExtents' protocol requests (CVE-2007-4568). Sean Larsson also
discovered an error in the swap_char2b() function possibly leading to a
heap corruption when handling the same protocol requests
The first issue would allow a local attacker to change permissions of
arbitrary files to be world-writable by performing a symlink attack.
The second and third issues would allow a local attacker to execute
arbitrary code with privileges of the user running the X Font Server,
There is no known workaround at this time.
