Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)
The vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
2) Double Free (CVE-ID: CVE-2022-4450)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.
3) Use-after-free (CVE-ID: CVE-2023-0215)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
4) Release of invalid pointer or reference (CVE-ID: CVE-2023-0216)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to invalid pointer dereference in d2i_PKCS7 functions. A remote attacker can perform a denial of service (DoS) attack.
5) NULL pointer dereference (CVE-ID: CVE-2023-0217)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when validating the DSA public key. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
6) NULL pointer dereference (CVE-ID: CVE-2023-0401)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error during PKCS7 data verification. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) Out-of-bounds read (CVE-ID: CVE-2022-4203)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when performing name constraint checking of the X.509 certificates. A remote attacker can pass a specially crafted X.509 certificate to the affected server, trigger an out-of-bounds read error and read contents of memory on the system.
8) Prototype pollution (CVE-ID: CVE-2020-28458)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
9) Cross-site scripting (CVE-ID: CVE-2021-23445)
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. 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.
10) Prototype pollution (CVE-ID: CVE-2019-11358)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
11) Cross-site scripting (CVE-ID: CVE-2020-11023)
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 passing <option> elements to jQuery’s DOM manipulation methods. A remote attacker can execute arbitrary JavaScript 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.
12) Cross-site scripting (CVE-ID: CVE-2020-7656)
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 within the load() function. A remote attacker can pass specially crafted HTML code to the application and execute it in browser in security context of the affected 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.
