Säkerhetsbulletin från Debian

DSA-1869-1 curl -- otillräcklig kontroll av indata

Rapporterat den:

2009-08-19

Berörda paket:

curl

Sårbara:

Referenser i säkerhetsdatabaser:

I Debians felrapporteringssystem: Fel 541991.
I Mitres CVE-förteckning: CVE-2009-2417.

Ytterligare information:

Det upptäcktes att curl, en client och ett bibliotek för att hämta filer från servrar med hjälp av HTTP, HTTPS eller FTP, är sårbart för nullprefixattacker mot SSL-/TLS-certifikat (Null Prefix Attacks Against SSL/TLS Certificates) som nyligen publicerades på Blackhat-konferensen. Detta tillåter en angripare att genomföra oupptäckta mannen-i-mitten-attacker med hjälp av ett specialskrivet ITU-T X.509-certifikat med en injicerad null-byte i något eller några av fälten subjectAltName och Common Name.

För den gamla stabila utgåvan (Etch) har detta problem rättats i version 7.15.5-1etch3.

För den stabila utgåvan (Lenny) har detta problem rättats i version 7.18.2-8lenny3.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) kommer detta problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era curl-paket.
