DSA-1869-1 curl -- utilstrækkelig fornuftighedskontrol af inddata

Rapporteret den:

19. aug 2009

Berørte pakker:

curl

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 541991.
I Mitres CVE-ordbog: CVE-2009-2417.

Yderligere oplysninger:

Man opdagede at curl, en klient og et bibliotek til at hente filer fra servere ved hjælp af HTTP, HTTPS eller FTP, var sårbar over for det nyligt offentliggjorte sårbarhed "Null Prefix Attacks Against SSL/TLS Certificates" på Blackhat-konferencen. Det gjorde det muligt for en angriber at udføre uopdagede manden i midten-angreb gennem et fabrikeret ITU-T X.509-certifikat med en indsprøjtet null-byte i feltet Common Name.

I den gamle stabile distribution (etch), er dette problem rettet i version 7.15.5-1etch3.

I den stabile distribution (lenny), er dette problem rettet i version 7.18.2-8lenny3.

I distributionen testing (squeeze) og i den ustabile (sid) distribution, vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine curl-pakker.
