Slackware64-14.2 ChangeLog (2021-01-26)

  • patches/packages/sudo-1.9.5p2-x86_64-1_slack14.2.txz
    When invoked as sudoedit, the same set of command line options
    are now accepted as for “sudo -e”. The -H and -P options are
    now rejected for sudoedit and “sudo -e” which matches the sudo
    1.7 behavior. This is part of the fix for CVE-2021-3156.
    Fixed a potential buffer overflow when unescaping backslashes
    in the command's arguments. Normally, sudo escapes special
    characters when running a command via a shell (sudo -s or sudo
    -i). However, it was also possible to run sudoedit with the -s
    or -i flags in which case no escaping had actually been done,
    making a buffer overflow possible. This fixes CVE-2021-3156.
