Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Security restrictions bypass (CVE-ID: CVE-2018-4293)
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to an error in cookie management. A local attacker can run a specially crafted application and cause cookies unexpectedly persist in Safari.
2) Memory corruption (CVE-ID: CVE-2018-4290)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to boundary error when processing an emoji under certain configurations. A remote attacker can trick the victim into opening a specially crafted input, trigger memory corruption and cause the service to crash.
3) Out-of-bounds read (CVE-ID: CVE-2018-4282)
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to improper input validation. A local attacker can run a specially crafted application, trigger out-of-bounds read and read kernel memory.
4) Memory corruption (CVE-ID: CVE-2018-4280)
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to boundary error when processing malicious application. A local attacker can use a specially crafted application, trigger memory corruption and gain elevated privileges.
5) Out-of-bounds read (CVE-ID: CVE-2018-4248)
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A local attacker can run a specially crafted application, trigger out-of-bounds read and read restricted memory.
6) Spoofing attack (CVE-ID: CVE-2018-4277)
The vulnerability allows a remote attacker to perform spoofing attack.
