Description
This security bulletin contains information about 9 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-2018-12362)
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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
