Description
This security bulletin contains information about 18 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-12359)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to buffer overflow when rendering canvas content while adjusting the height and width of the <canvas> element dynamically. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger out-of-bounds write and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Use-after-free error (CVE-ID: CVE-2018-12360)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to use-after-free vulnerability when deleting an input element during a mutation event handler triggered by focusing that element. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Integer overflow (CVE-ID: CVE-2018-12361)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the SwizzleData code while calculating buffer sizes. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Same-origin policy bypass (CVE-ID: CVE-2018-12358)
The vulnerability allows a remote attacker to bypass same-origin policy on the target system.The weakness exists due to open redirect. A remote attacker can use redirect the victim into malicious website, avoid the tainting of cross-origin resources in some instances and read responses which are supposed to be opaque.
5) Integer overflow (CVE-ID: CVE-2018-12362)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Type confusion (CVE-ID: CVE-2018-5156)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists when capturing a media stream when the media source type is changed as the capture is occurring. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger type confusion and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Use-after-free error (CVE-ID: CVE-2018-12363)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to use-after-free error when script uses mutation events to move DOM nodes between documents. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Cross-site request forgery (CVE-ID: CVE-2018-12364)
The vulnerability allows a remote attacker to perform CSRF attack.The weakness exists due to insufficient CSRF protections. A remote attacker can use NPAPI plugins, such as Adobe Flash, send non-simple cross-origin requests, make a same-origin POST that does a 307 redirect to the target site, bypass CORS and conduct cross-site request forgery (CSRF) attacks.
9) Information disclosure (CVE-ID: CVE-2018-12365)
The vulnerability allows a remote attacker to obtain potentially sensitive information.The weakness exists due to a compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. A remote attacker can gain access to private local files.
10) Integer overflow (CVE-ID: CVE-2018-12371)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the Skia library when allocating memory for edge builders on some systems with at least 16 GB of RAM. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) Out-of-bounds read (CVE-ID: CVE-2018-12366)
The vulnerability allows a remote attacker to obtain potentially sensitive information.The weakness exists due to an invalid grid size during QCMS (color profile) transformations. A remote attacker can trigger out-of-bounds read interpreted as a float value and access private data from the output.
12) Timing attack (CVE-ID: CVE-2018-12367)
The vulnerability allows a remote attacker to conduct timing attack.The weakness exists due to in the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. A remote attacker can use PerformanceNavigationTiming as a precision timer and conduct timing attack and gain access to arbitrary data.
13) Improper input validation (CVE-ID: CVE-2018-12368)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to iWindows 10 does not warn users before opening executable files with the SettingContent-msextension even when they have been downloaded from the internet and have the "Mark of the Web". A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, use WebExtension with the limited downloads.openpermission and execute arbitrary code without user interaction on Windows 10 systems
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Security restrictions bypass (CVE-ID: CVE-2018-12369)
The vulnerability allows a remote attacker to bypass security restrictions on the target system.The weakness exists due to WebExtensions bundled with embedded experiments were not correctly checked for proper authorization. A remote attacker can use a malicious WebExtension to bypass security restrictions and gain full browser permissions.
15) Security restrictions bypass (CVE-ID: CVE-2018-12370)
The vulnerability allows a remote attacker to bypass security restrictions on the target system.The weakness exists due to in Reader View SameSite cookie protections are not checked on exiting. A remote attacker can trigger a payload when Reader View is exited if loaded by a malicious site while Reader mode is active, bypass CSRF protections and possibly conduct CSRF attack.
16) Memory corruption (CVE-ID: CVE-2018-5186)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when handling malicious input. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
17) Memory corruption (CVE-ID: CVE-2018-5187)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when handling malicious input. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
18) Memory corruption (CVE-ID: CVE-2018-5188)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when handling malicious input. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
