Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-1020)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when Internet Explorer improperly accesses objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Memory corruption (CVE-ID: CVE-2018-0991)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when Internet Explorer improperly accesses objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Memory corruption (CVE-ID: CVE-2018-1018)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when Internet Explorer improperly accesses objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Memory corruption (CVE-ID: CVE-2018-0870)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when Internet Explorer improperly accesses objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Memory corruption (CVE-ID: CVE-2018-0997)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when Internet Explorer improperly accesses objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Information disclosure (CVE-ID: CVE-2018-0987)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to improper handling of objects in memory by the scripting engine in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and gain access to potentially sensitive information.
7) Memory corruption (CVE-ID: CVE-2018-0988)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to in the way the scripting engine handles objects in memory in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
8) Information disclosure (CVE-ID: CVE-2018-0989)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to improper handling of objects in memory by the scripting engine in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and gain access to potentially sensitive information.
9) Information disclosure (CVE-ID: CVE-2018-1000)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to improper handling of objects in memory by the scripting engine in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and gain access to potentially sensitive information.
10) Information disclosure (CVE-ID: CVE-2018-0981)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists due to improper handling of objects in memory by the scripting engine in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and gain access to potentially sensitive information.
11) Memory corruption (CVE-ID: CVE-2018-1001)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to in the way the scripting engine handles objects in memory in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
12) Memory corruption (CVE-ID: CVE-2018-0996)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to in the way the scripting engine handles objects in memory in Internet Explorer. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.
