>      Security Level: None
>          Components: Resources/res_pjsip
>    Affects Versions: 13.9.1
>         Environment: Debian Sid
>            Reporter: erebus
>            Severity: Minor

> In source file asterisk/res/res_pjsip/location.c, there are several lines which pass AOR identifiers into regular expressions without proper escaping.
> For AORs that include regex metacharacters (such as +0000, bobby+tables or Tables*Bobby), this means that the resulting regex will be incorrect, breaking contact lookups and inbound calling.
> I suggest that AOR identifiers be escaped before being inserted into regular expressions.
