Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Incorrect calculation (CVE-ID: CVE-2023-24532)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars.


2) Resource exhaustion (CVE-ID: CVE-2023-24534)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when parsing HTTP and MIME headers in net/textproto. A remote attacker can cause an HTTP server to allocate large amounts of memory from a small request and perform a denial of service (DoS) attack.


3) Resource management error (CVE-ID: CVE-2023-24536)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within mime/multipart and net/textproto components when parsing multipart forms. A remote attacker can pass specially crafted request to the application and perform a denial of service (DoS) attack.


4) Infinite loop (CVE-ID: CVE-2023-24537)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop when calling any of the Parse functions on Go source code which contains //line directives with very large line numbers. A remote attacker can consume all available system resources and cause denial of service conditions.


5) Code Injection (CVE-ID: CVE-2023-24538)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in html/template when handling JavaScript templates that contain backticks in code. If a template contains a Go template action within a JavaScript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary JavaScript code into the Go template.


6) Cross-site scripting (CVE-ID: CVE-2023-24539)

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 handling angle brackets in CSS context. A remote attacker can inject 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.


7) 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.


8) Buffer overflow (CVE-ID: CVE-2020-24736)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when executing a crafted SELECT query. A local user can execute a specially crafted query to trigger memory corruption and perform a denial of service (DoS) attack.


9) NULL pointer dereference (CVE-ID: CVE-2022-36227)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in libarchive. A remote attacker can pass a specially crafted archive to the application and perform a denial of service (DoS) attack.


10) Input validation error (CVE-ID: CVE-2023-1667)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to multiple errors in kex implementation, related to kex guessing algorithm. A remote attacker can bypass implemented security restrictions.


11) Improper Authentication (CVE-ID: CVE-2023-2283)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error within the pki_verify_data_signature() function in pki_crypto.c. The pki_key_check_hash_compatible() function can return SSH_OK value if memory allocation error happens later in the function. The  A remote attacker can bypass authentication process and gain unauthorized access to the system.


12) Improper Privilege Management (CVE-ID: CVE-2023-26604)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper privilege management for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.


13) State Issues (CVE-ID: CVE-2023-27535)

The vulnerability allows a remote attacker to gain unauthorized access to FTP server.

The vulnerability exists due to cURL will reuse a previously created FTP connection even when one or more options had been changed that could have made the effective user a very different one. A remote attacker can connect to the FTP server using credentials supplied by another user and gain access to otherwise restricted functionality.

The settings in questions are CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC and CURLOPT_USE_SSL level.
