Hello,
savetextmode, a utility that comes with SVGATextMode 1.8, saves the text
mode data in /tmp, in two files with the mode 644:
[/tmp]
root@Death# ls -lA
total 1
drwxrwxrwx 2 root gods 1024 Sep 24 1998 .X11-unix/
[/tmp]
root@Death# savetextmode
svgalib: Using S3 driver (Trio64, 4096K).
svgalib: s3: chipsets newer than S3-864 is not supported well yet.
svgalib: RAMDAC: Trio64: MCLK = 47.131 MHz
[/tmp]
root@Death# ls -lA
total 35
drwxrwxrwx 2 root gods 1024 Sep 24 1998 .X11-unix/
-rw-r--r-- 1 root gods 32768 Oct 21 22:56 fontdata
-rw-r--r-- 1 root gods 385 Oct 21 22:56 textregs
Also, I would like to add that savetextmode accepts no parameters.
So... any user on the system that knows that the root is using
SVGATextMode could link any of the files to a file that he wants to be
overwritten.
The e-mail is cc-ed to the maker of SVGATextMode, koen.gadeyne@barco.com.
