Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. ------------------------------------------------------------------------- PROBLEM: The current directory is in the root user's PATH after logging in using CDE. PLATFORM: HP 9000 series 700/800 at HP-UX revision 10.X DAMAGE: Increase in privileges.. SOLUTION: Modify /usr/dt/bin/Xsession until a patch is available. AVAILABILITY: This advisory will be updated when patches are available. CHANGE SUMMARY: HTML to text conversion instructions for script added. ------------------------------------------------------------------------- I. A. Background - The PATH environemnt variable is constructed from several sources including dtsearchpath and scripts in /etc/dt/config/Xsession.d/ and /usr/dt/config/Xsession.d/. The resulting PATH contains the string "::" which will be interpreted as the current directory. The root user should not have the current directory in the PATH. B. Fixing the problem - Since the PATH environment variable can be affected by dtsearchpath and several scripts, the recommended solution is to clean up the root user's PATH after is has been created. **REVISED 01** Note: This file is in HTML format. If you are editing the text version from a mailing the line below: for (i=3D1; i<=3Dn; i++) { must be changed. Replace the characters between the second "i" and the "=3Dn" with the single "less than" character (ascii 0x3c). The line will then read: for (i=3D1; iX=3Dn; i++) { where X stands for the "less than" character. In /usr/dt/bin/Xsession just before this: # #########################################################################= ## # # Startup section. Add this: ###################### Clean up $PATH for root ########################## if [ "$USER" =3D "root" ] then Log "Clean up PATH for root user" Log "Old PATH =3D $PATH" PATH=3D`echo $PATH | awk ' { # Remove elements from PATH that are # (a) "." # (b) "" # (c) blank # gsub (" ",":", $0) # Substitite ":" for each blank n =3D split ($0, path, ":") # Split into elements with ":" as delimiter first =3D 1 # To suppress leading ":" in new PATH for (i=3D1; i<=3Dn; i++) { len =3D length(path[i]) dot =3D index(path[i], ".") dot_only =3D 0 if ((len =3D=3D 1) && (dot=3D=3D1)) { dot_only =3D 1 } # print element if it is not "" and not "." if (!(len=3D=3D0) && !(dot_only=3D=3D1)) { if(first !=3D 1) { printf (":") # if not first element, print ":" in front } printf ("%s",path[i]) first =3D 0 } } } END { printf ("\n") }'` Log "New PATH =3D $PATH" fi ###################### End - Clean up $PATH for root #################### C.
