Slackware: 2021-026-01: sudo Security Update
Summary
Here are the details from the Slackware 14.2 ChangeLog: patches/packages/sudo-1.9.5p2-i586-1_slack14.2.txz: Upgraded. 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. For more information, see: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3156 (* Security fix *)
