CVE-2004-1268
lppasswd in CUPS 1.1.22 ignores write errors when modifying the CUPS
passwd file, which allows local users to corrupt the file by filling
the associated file system and triggering the write errors.

CVE-2004-1269
lppasswd in CUPS 1.1.22 does not remove the passwd.new file if it
encounters a file-size resource limit while writing to passwd.new,
which causes subsequent invocations of lppasswd to fail.

CVE-2004-1270
lppasswd in CUPS 1.1.22, when run in environments that do not ensure
that file descriptors 0, 1, and 2 are open when lppasswd is called,
does not verify that the passwd.new file is different from STDERR,
which allows local users to control output to passwd.new via certain
user input that triggers an error message.");
