191 | safe? |
| 191 | Likely not. While I honestly try to make it secure, and am probably |
192 | It should be, starting with release 7.1. You are encouraged to |
| 192 | not bad at it, I think it is simply unreasonable to expect all of |
193 | properly install urxvt with privileges necessary for your OS now. |

194 | |
| 194 | itself to all be secure. Also, rxvt-unicode disables some options |
|
|
| 195 | when it detects that it runs setuid or setgid, which is not nice. |
195 | When rxvt-unicode detects that it runs setuid or setgid, it will |
| 196 | Besides, with the embedded perl interpreter the possibility for |
196 | fork into a helper process for privileged operations (pty handling |
| 197 | security problems easily multiplies. |
197 | on some systems, utmp/wtmp/lastlog handling on others) and drop |
|
|
198 | privileges immediately. This is much safer than most other terminals |
|
|
199 | that keep privileges while running (but is more relevant to urxvt, |
|
|
200 | as it contains things as perl interpreters, which might be "helpful" |
|
|
201 | to attackers). |
| 198 | |
202 | |
| 199 | Elevated privileges are only required for utmp and pty operations on |
203 | This forking is done as the very first within main(), which is very |
| 200 | some systems (for example, GNU/Linux doesn't need any extra |
204 | early and reduces possible bugs to initialisation code run before |
| 201 | privileges for ptys, but some need it for utmp support). It is |
205 | main(), or things like the dynamic loader of your system, which |
| 202 | planned to mvoe this into a forked handler process, but this is not |
206 | should result in very little risk. |
| 203 | yet done. |
|
|
| 204 | |
|
|
| 205 | So, while setuid/setgid operation is supported and not a problem on |
|
|
| 206 | your typical single-user-no-other-logins unix desktop, always |
|
|
| 207 | remember that its an awful lot of code, most of which isn't checked |
|
|
| 208 | for security issues regularly. |
