ISS X-Force Database: mozilla-nss-security-bypass(30098): Mozilla Network Security Services RSA signature validation security bypass

Mozilla Network Security Services RSA signature validation security bypass

mozilla-nss-security-bypass (30098)

Medium Risk

Description:

Mozilla Firefox, Thunderbird, and SeaMonkey could allow a remote attacker to bypass security, caused by improper verification of RSA signatures by the Network Security Services (NSS) library. A remote attacker could exploit this vulnerability to forge PKCS #1 v1.5 signatures and bypass security restrictions.

CVE-2006-4340: Mozilla Network Security Service (NSS) library before 3.11.3, as used in Mozilla Firefox before 1.5.0.7, Thunderbird before 1.5.0.7, and SeaMonkey before 1.0.5, when using an RSA key with exponent 3, does not properly handle extra data in a signature, which allows remote attackers to forge signatures for SSL/TLS and email certificates, a similar vulnerability to CVE-2006-4339. NOTE: on 20061107, Mozilla released an advisory stating that these versions were not completely patched by MFSA2006-60. The newer fixes for 1.5.0.7 are covered by CVE-2006-5462.
CVE-2006-5462: Mozilla Network Security Service (NSS) library before 3.11.3, as used in Mozilla Firefox before 1.5.0.8, Thunderbird before 1.5.0.8, and SeaMonkey before 1.0.6, when using an RSA key with exponent 3, does not properly handle extra data in a signature, which allows remote attackers to forge signatures for SSL/TLS and email certificates. NOTE: this identifier is for unpatched product versions that were originally intended to be addressed by CVE-2006-4340.
