Slackware and other distros patch sudo vulnerability |
 |
The week began with an announcement about a serious vulnerability found in the sudo tool. The sudo command is installed on most Linux distributions and is used to allow one user to run commands as another. Typically this allows the owner of a computer to run commands as the root user, performing admin tasks while still logged in under their regular account. The sudo website explained the issue: "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." Most major distributions quickly patched vulnerable versions of the sudo tool with some, including Slackware also provided additional details on the exploit. |
