Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2023-29400)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when processing HTML attributes. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-2454)
The vulnerability allows a remote user to execute arbitrary code on the system.
The vulnerability exists due to improperly imposed security restrictions. A remote database user with CREATE privilege can bypass protective search_path changes via "CREATE SCHEMA ... schema_element" command and execute arbitrary code on the system.
3) Use-after-free (CVE-ID: CVE-2022-43552)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error while processing denied requests from HTTP proxies when using SMB or TELNET protocols. A remote attacker can trigger a use-after-free error and crash the application.
4) Security features bypass (CVE-ID: CVE-2022-43551)
The vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists in the way curl handles IDN characters in hostnames. The HSTS mechanism could be bypassed if the hostname in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Then in a subsequent request it does not detect the HSTS state and makes a clear text transfer.
5) Input validation error (CVE-ID: CVE-2023-24329)
The vulnerability allows a remote attacker to bypass implemented filters.
The vulnerability exists due to insufficient validation of URLs that start with blank characters within urllib.parse component of Python. A remote attacker can pass specially crafted URL to bypass existing filters.
6) Security features bypass (CVE-ID: CVE-2023-2455)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to incomplete fix for #VU40402 (CVE-2016-2193) that did not anticipate a scenario involving function inlining. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.
This affects only databases that have used CREATE POLICY to define a row security policy.
7) Input validation error (CVE-ID: CVE-2022-35252)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an
HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.
