Yderligere oplysninger:

Flere sårbarheder er opdaget af opstrøm i ethereal, et netværksanalyseringsprogram. Projektet Common Vulnerabilities and Exposures har fundet frem til følgende problemer:

CAN-2003-0925
Et bufferoverløb gør det muligt for fjernangribere at iværksætte et lammelsesangreb og potentielt udføre vilkårlig kode via en misdannet GTP MSISDN-streng.
CAN-2003-0926
Ved hjælp af visse misdannede ISAKMP- eller MEGACO-pakker kan fjernangribere iværksætte et lammelsesangreb (systemnedbrud).
CAN-2003-0927
Et stakbaseret bufferoverløb gør det muligt for fjernangribere at iværksætte et lammelsesangreb (systemnedbrud) og potentielt udføre vilkårlig kode ved hjælp af SOCKS-dissector'en.
CAN-2003-1012
SMB-dissector'en gør det muligt for fjernangribere at iværksætte et lammelsesangreb ved hjælp af en misdannet SMB-pakke som udløser en segmenteringsfejl under behandlingen af valgte pakker.
CAN-2003-1013
Q.931-dissector'en gør det muligt for fjernangribere at iværksætte et lammelsesangreb (systemnedbrud) ved hjælp af en misdannet Q.931, hvilket udløser en nul-reference.

I den stabile distribution (woody) er dette problem rettet i version 0.9.4-1woody6.

I den ustabile distribution (sid) er dette problem rettet i version 0.10.0-1.

Vi anbefaler at du opgraderer dine ethereal- og tethereal-pakker.
