Descriptions

The _rl_tropen function in util.c in GNU readline before 6.3 patch 3 allows local users to create or overwrite arbitrary files via a symlink attack on a /var/tmp/rltrace.[PID] file.

La función _rl_tropen en util.c en GNU readline anterior a 6.3 patch 3 permite a usuarios locales crear o sobrescribir ficheros arbitrarios a través de un ataque de enlace simbólico sobre un fichero /var/tmp/rltrace.[PID].

Steve Kemp discovered the _rl_tropen() function in readline insecurely handled a temporary file. This could allow a local attacker to perform symbolic link attacks. Also, upstream patches have been added to fix an infinite loop in vi input mode, and to fix an issue with slowness when pasting text.
