Multiple vulnerabilities have been identified in Mozilla Thunderbird, which could be exploited by attackers to take complete control of an affected system or cause a denial of service.
The first issue is due to memory corruption errors in the layout, SVG and JavaScript engines, which could be exploited by attackers to crash a vulnerable application or execute arbitrary commands.
The second vulnerability is due to buffer overflow errors in the Network Security Services (NSS) when processing a certificate with a public key too small to encrypt the "Master Secret" or when handling invalid parameters while negotiating an SSLv2 session, which could be exploited by attackers to crash a vulnerable application or execute arbitrary commands.
The third issue is due to a memory corruption error when handling "onUnload" events and self-modifying "document.write()" calls, which could be exploited by attackers to crash a vulnerable application or execute arbitrary commands.
