Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Two vulnerabilities have been reported in Network Security Services (NSS), which potentially can be exploited by malicious people to compromise a vulnerable system.

1) An integer underflow error when processing SSLv2 server messages can be exploited to cause a heap-based buffer overflow via a certificate with a public key too small to encrypt the "Master Secret".

2) An integer underflow error when processing SSLv2 client master keys can be exploited to cause a stack-based buffer overflow via specially crafted parameters during an SSLv2 handshake.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.

The vulnerabilities are reported in versions 3.10 and 3.11.3. Other versions may also be affected.
