169 | safe? |
167 | Likely not. While I honestly try to make it secure, and am probably |
170 | It should be, starting with release 7.1. You are encouraged to |
168 | not bad at it, I think it is simply unreasonable to expect all of |
171 | properly install urxvt with privileges necessary for your OS now. |
169 | freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode |
172 | |
170 | itself to all be secure. Also, rxvt-unicode disables some options |
|
|
171 | when it detects that it runs setuid or setgid, which is not nice. |
173 | When rxvt-unicode detects that it runs setuid or setgid, it will |
172 | Besides, with the embedded perl interpreter the possibility for |
174 | fork into a helper process for privileged operations (pty handling |
173 | security problems easily multiplies. |
175 | on some systems, utmp/wtmp/lastlog handling on others) and drop |
|
|
176 | privileges immediately. This is much safer than most other terminals |
|
|
177 | that keep privileges while running (but is more relevant to urxvt, |
|
|
178 | as it contains things as perl interpreters, which might be "helpful" |
|
|
179 | to attackers). |
174 | |
180 | |
175 | Elevated privileges are only required for utmp and pty operations on |
181 | This forking is done as the very first within main(), which is very |
176 | some systems (for example, GNU/Linux doesn't need any extra |
182 | early and reduces possible bugs to initialisation code run before |
177 | privileges for ptys, but some need it for utmp support). It is |
183 | main(), or things like the dynamic loader of your system, which |
178 | planned to mvoe this into a forked handler process, but this is not |
184 | should result in very little risk. |

|

180 | |
|
|
181 | So, while setuid/setgid operation is supported and not a problem on |
|
|
182 | your typical single-user-no-other-logins unix desktop, always |
|
|
183 | remember that its an awful lot of code, most of which isn't checked |
|
|
184 | for security issues regularly. |
