Vulnerability from variot

A logic issue existed in the handling of answering phone calls. The issue was addressed with improved state management. This issue is fixed in iOS 12.4. The initiator of a phone call may be able to cause the recipient to answer a simultaneous Walkie-Talkie connection. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Arbitrary code execution * Insufficient access restrictions * information leak * Service operation interruption (DoS) * Information falsification * Privilege escalation * Sandbox avoidance. Apple iOS is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. Telephony is one of the telephony components. A security vulnerability exists in the Telephony component of Apple's iOS prior to 12.4. An attacker can exploit this vulnerability to make the receiver connect to the "walkie-talkie" at the same time

    "data": "A logic issue existed in the handling of answering phone calls. The issue was addressed with improved state management. This issue is fixed in iOS 12.4. The initiator of a phone call may be able to cause the recipient to answer a simultaneous Walkie-Talkie connection. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Arbitrary code execution * Insufficient access restrictions * information leak * Service operation interruption (DoS) * Information falsification * Privilege escalation * Sandbox avoidance. Apple iOS is prone to a security-bypass vulnerability. \nAn attacker can exploit this issue to bypass security restrictions and  perform unauthorized actions. This may aid in further attacks. Telephony is one of the telephony components. A security vulnerability exists in the Telephony component of Apple\u0027s iOS prior to 12.4. An attacker can exploit this vulnerability to make the receiver connect to the \"walkie-talkie\" at the same time",
