Description

This security bulletin contains information about 11 secuirty vulnerabilities.

1) 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.

2) 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.

3) 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.

4) 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.

5) 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.

6) 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.

7) 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.

8) 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.

9) Memory leak (CVE-ID: CVE-2018-12372)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to decrypted S/MIME parts, when included in HTML crafted for an attack, can leak plaintext when included in a a HTML reply/forward. A remote attacker can trigger memory leak and gain access to arbitrary data.

10) Memory leak (CVE-ID: CVE-2018-12373)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to dDecrypted S/MIME parts hidden with CSS or <plaintext> can leak plaintext when included in a HTML reply/forward. A remote attacker can trigger memory leak and gain access to arbitrary data.

11) Memory leak (CVE-ID: CVE-2018-12374)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to plaintext of decrypted emails can leak through. A remote attacker can submit an embedded form by press enter key within a text input field, submit an embedded form, trigger memory leak and gain access to arbitrary data.
