Description:
HP issued a security advisory for HP/UX warning that the pcltotiff file conversion utility has unsafe permissions that could cause a denial of service condition. It may also allow a local user to gain additional privileges.
The affected file is:
/opt/sharedprint/bin/pcltotiff has unsafe permissions.
This file is reportedly assigned with group "bin" with set group id permissions, which is required to allow pcltotiff to read files in /usr/lib/X11/fonts/ifo.st/typefaces/.
An unspecified issue with the set group id permissions may allow a local user to cause an unspecified denial of service condition. Although the vendor does not confirm this, it may also allow a local user to gain additional "bin" privileges.
|
Impact:
A local user could cause an unspecified denial of service condition. Although the vendor does not confirm this, it may also allow a local user to gain additional "bin" privileges.
|
Solution:
As an interim measure, the vendor recommends that users change the permissions on /opt/sharedprint/bin/pcltotiff. Read the source message for details. Patches will be released at a later date.

Remove the set group id permissions from pcltotiff and
allow read access to /usr/lib/X11/fonts/ifo.st/typefaces/.
C. Recommended solution
/sbin/chmod 555 /opt/sharedprint/bin/pcltotiff
/sbin/chmod o+r /usr/lib/X11/fonts/ifo.st/typefaces/*
To avoid swverify errors:
**REVISED 01:
#!/sbin/sh
/usr/sbin/swmodify -x files='/opt/sharedprint/bin/pcltotiff' \
SharedPrint.SHPRNT-PCL
for i in `/sbin/ls /usr/lib/X11/fonts/ifo.st/typefaces`
do
/usr/sbin/swmodify \
-x files="/usr/lib/X11/fonts/ifo.st/typefaces/$i" \
