| Doc Text: |
A heap-based buffer overflow was found in the NSC_EncryptUpdate() function in Mozilla nss. A remote attacker could trigger this flaw via SRTP encrypt or decrypt operations, to execute arbitrary code with the permissions of the user running the application (compiled with nss). While the attack complexity is high, the impact to confidentiality, integrity, and availability are high as well.
