Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2023-44487)

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.


2) Resource exhaustion (CVE-ID: CVE-2023-39325)

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

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Resource exhaustion (CVE-ID: CVE-2023-45142)

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

The vulnerability exists due to incorrect processing of HTTP header User-Agent and HTTP method. A remote attacker can send multiple requests with long randomly generated HTTP methods or/and User agents and consume memory resources, leading to a denial of service condition.

4) NULL pointer dereference (CVE-ID: CVE-2022-4285)

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 parsing an ELF file containing corrupt symbol version information. A remote attacker can pass a specially crafted file to the application and perform a denial of service (DoS) attack.


5) Buffer overflow (CVE-ID: CVE-2022-4904)

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

The vulnerability exists due to a boundary error within the config_sortlist() function. A local user can trigger memory corruption and perform a denial of service (DoS) attack.


6) Incorrect Regular Expression (CVE-ID: CVE-2022-40897)

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

The vulnerability exists due to insufficient input validation when processing HTML content. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


7) Memory leak (CVE-ID: CVE-2023-2602)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in the error handling in the __wrap_pthread_create() function. A remote attacker can send a specially crafted request, exploit vulnerability to exhaust the process memory and cause a denial of service condition.


8) PHP file inclusion (CVE-ID: CVE-2023-2603)

The vulnerability allows a remote attacker to include and execute arbitrary PHP files on the server.

The vulnerability exists due to incorrect input validation when including PHP files in web/ajax/modal.php. A remote non-authenticated attacker can send a specially crafted HTTP request to the affected application, include and execute arbitrary PHP code on the system with privileges of the web server.


9) Use-after-free (CVE-ID: CVE-2023-4806)

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

The vulnerability exists due to a use-after-free error within the getaddrinfo() function. A remote attacker can perform a denial of service (DoS) attack.



10) Use-after-free (CVE-ID: CVE-2023-4813)

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 gaih_inet() function when the getaddrinfo() function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.



11) Buffer overflow (CVE-ID: CVE-2023-29491)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing malformed data in a terminfo database file. A local user can trigger memory corruption and execute arbitrary code on the target system.
