Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2022-25315)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in storeRawNames function. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Use-after-free (CVE-ID: CVE-2022-26485)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing XSLT parameter. A remote attacker can trick the victim to open a specially crafted web page, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
Note, the vulnerability is being actively exploited in the wild.
3) Improper access control (CVE-ID: CVE-2022-26386)
The vulnerability allows a local user to gain access to victim's downloads.
The vulnerability exists due to browser stores files in the /tmp folder, which is accessible by all local users. A local user can read files from this folder and gain access to potentially sensitive information.
Note, the vulnerability affects Firefox ESR on macOS and Linux.
4) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-26383)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error when resizing a popup after requesting fullscreen access. The popup would not display the fullscreen notification, which allows a remote attacker to perform spoofing attack.
5) Security restrictions bypass (CVE-ID: CVE-2022-26384)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a logic error when processing iframes. If an attacker can control the contents of an iframe sandboxed with allow-popups but not allow-scripts, it is possible to craft a link that, when clicked, would lead to JavaScript execution in violation of the sandbox.
6) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2022-26387)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to a race condition when verifying signatures during Firefox add-on installation. A remote attacker can replace the underlying add-on file while the user was confirming the prompt and install a malicious add-on on the system.
7) Use-after-free (CVE-ID: CVE-2022-26381)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content A remote attacker can trigger a use-after-free by forcing a text reflow in an SVG object and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
8) Use-after-free (CVE-ID: CVE-2022-26486)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing messages in the WebGPU IPC framework. A remote attacker can trick the victim to open a specially crafted web page, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
Note, the vulnerability is being actively exploited in the wild.
9) Input validation error (CVE-ID: CVE-2022-25236)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper protection against insertion of namesep characters into namespace URIs in xmlparse.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
10) Code Injection (CVE-ID: CVE-2022-25235)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to the affected application lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
