7.5 HIGH — AV:N/AC:L/Au:N/C:P/I:P/A:P

Description

Buffer overflow in the International Domain Name (IDN) support in Mozilla Firefox 1.0.6 and earlier, and Netscape 8.0.3.3 and 7.2, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a hostname with all "soft" hyphens (character 0xAD), which is not properly handled by the NormalizeIDN call in nsStandardURL::BuildNormalizedSpec.

Affected configurations

• mozilla firefox 1.0 • mozilla firefox 1.0.1 • mozilla firefox 1.0.2 • mozilla firefox 1.0.3 • mozilla firefox 1.0.4 • mozilla firefox 1.0.5 • mozilla firefox 1.0.6 • mozilla firefox 1.5
