Description
This security bulletin contains information about 9 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2017-13833)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to out-of-bounds read in the kernel component. A local attacker can use a specially crafted application, trigger out-of-bounds read error and read arbitrary files.
2) Memory corruption (CVE-ID: CVE-2017-13855)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to memory handling error in the kernel component. A local attacker can use a specially crafted application, trigger memory handling error and read arbitrary files.
3) Memory corruption (CVE-ID: CVE-2017-13861)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear
The vulnerability allows a local attacker to execute arbitrary code o the target system.
The weakness exists due to boundary error in IOSurface. A local attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
4) Memory corruption (CVE-ID: CVE-2017-13862)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the kernel component. A local attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
5) Improper input validation (CVE-ID: CVE-2017-13865)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper input validation in the kernel component. A local attacker can use a specially crafted application, trigger input validation flaw and read arbitrary files.
6) Memory corruption (CVE-ID: CVE-2017-13867)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the kernel component. A local attacker can use a specially crafted application, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
7) Improper input validation (CVE-ID: CVE-2017-13868)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper input validation in the kernel component. A local attacker can use a specially crafted application, trigger input validation flaw and read arbitrary files.
8) Improper input validation (CVE-ID: CVE-2017-13869)
CWE-ID: CWE-20 - Improper input validation
