Description

This security bulletin contains information about 4 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2017-16872)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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.
