I Debians fejlsporingssystem: Fejl 518423.
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 33962.
I Mitres CVE-ordbog: CVE-2009-0037.

Yderligere oplysninger:

David Kierznowski opdagede at libcurl, et filoverførselsbibliotek der understøtter flere protokoller, når det var opsat til at følge URL-viderestillinger automatisk, ikke betvivlede det nye mål. Da libcurl også understøtter URL'er af typen file:// og scp:// - afhængigt af opsætningen - kunne en ikke-betroet server anvende dette, til at blotlægge lokale filer, overskrive lokale filer eller endda udføre vilkårlig kode gennem en ondsindet URL-viderestilling.

Opdateringen indeholder en ny indstillingsmulighed kaldet CURLOPT_REDIR_PROTOCOLS, der som standard ikke gælder håndteringen af scp- og file-protokollerne.

I den gamle stabile distribution (etch) er dette problem rettet i version 7.15.5-1etch2.

I den stabile distribution (lenny) er dette problem rettet i version 7.18.2-8lenny2.

I den ustabile distribution (sid) er dette problem rettet i version 7.18.2-8.1.

Vi anbefaler at du opgraderer dine curl-pakker.
