Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Improper Certificate Validation (CVE-ID: CVE-2023-29409)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.
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-2023-44487)
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.
4) 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.
5) 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.
6) Out-of-bounds read (CVE-ID: CVE-2023-4527)
The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the getaddrinfo() function called with the AF_UNSPEC address family. A remote attacker with control over DNS server can send a DNS response via TCP larger than 2048 bytes, trigger an out-of-bounds read and crash the application or gain access to potentially sensitive information.
Successful exploitation of the vulnerability requires that system is configured with no-aaaa mode via /etc/resolv.conf.
7) 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.
8) 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.
9) Buffer overflow (CVE-ID: CVE-2023-4911)
The vulnerability allows a local user to escalate privileges on the system.
10) NULL pointer dereference (CVE-ID: CVE-2023-28484)
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 xmlSchemaFixupComplexType. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
11) Resource management error (CVE-ID: CVE-2023-29469)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources when working with hashes of empty dict strings. A remote attacker can and perform a denial of service (DoS) attack.
12) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).
13) External control of file name or path (CVE-ID: CVE-2023-38546)
The vulnerability allows an attacker to inject arbitrary cookies into request.
The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the
cookie-enable state is also cloned - but without cloning the actual
cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none (using the four ASCII letters, no quotes).
none - if such a file exists and is readable in the current directory of the program using libcurl. Remediation
