NewStart CGSL CORE 5.05 / MAIN 5.05 : nss Multiple Vulnerabilities (NS-SA-2020-0005)

high Nessus Plugin ID 133085

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has nss packages installed that are affected by multiple vulnerabilities:

 - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. (CVE-2019-11729)

 - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur.
 This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-11745)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL nss packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
