Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2017-16872)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error when parsing the numeric header fields in a SIP message. A remote attacker can use specially crafted invalid values, trigger buffer overflow and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
2) Integer overflow (CVE-ID: CVE-2017-16875)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the ioqueue component due to issuing a double key unregistration after a remote attacker initiates a socket connection with specific settings and sequences. A remote attacker can trigger integer overflow, ioqueue backends to reject future key registrations and cause the service to crash.
3) Integer overflow (CVE-ID: CVE-2018-1000098)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in pjmedia SDP parsing due to integer overflow. A remote attacker can submit a specially crafted message, trigger memory corruption and cause the service to crash.
4) NULL pointer dereference (CVE-ID: CVE-2018-1000099)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in pjmedia SDP parsing due to NULL pointer dereference. A remote attacker can submit a specially crafted message and cause the service to crash.
