Description

This security bulletin contains information about 18 secuirty vulnerabilities.


1) Inefficient regular expression complexity (CVE-ID: CVE-2024-45296)

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

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


2) Inefficient regular expression complexity (CVE-ID: CVE-2024-45813)

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

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


3) Integer overflow (CVE-ID: CVE-2021-43618)

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

The vulnerability exists due to integer overflow in mpz/inp_raw.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.


4) Out-of-bounds read (CVE-ID: CVE-2022-48554)

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

The vulnerability exists due to a boundary condition within the file_copystr() function in funcs.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and crash the application.


5) Out-of-bounds read (CVE-ID: CVE-2023-7104)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the sessionReadRecord() function in ext/session/sqlite3session.c when processing a corrupt changeset. A remote user can send a specially crafted request to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.


6) 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.



7) Insufficient verification of data authenticity (CVE-ID: CVE-2023-37920)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exist due to software recognizes "e-Tugra" root certificates, which were subject to an investigation prompted by reporting of security issues in their systems. An attacker with ability to generate certificates signed with the  compromised "e-Tugra" root certificate can perform MitM attack.


8) Resource exhaustion (CVE-ID: CVE-2023-47108)

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

The vulnerability exists due to grpc Unary Server Interceptor does not properly control consumption of internal resources when processing multiple requests. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


9) Missing Release of Resource after Effective Lifetime (CVE-ID: CVE-2024-2398)

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

The vulnerability exists due to an error when sending HTTP/2 server push responses with an overly large number of headers. A remote attacker can send PUSH_PROMISE frames with an excessive amount of headers to the application, trigger memory leak and perform a denial of service (DoS) attack.


10) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2024-3596)

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

The vulnerability exists due to use of a broken or risky cryptographic algorithm in RADIUS Protocol. A remote user can perform a man-in-the-middle (MitM) attack and gain access to target system.


11) Type Confusion (CVE-ID: CVE-2024-6119)

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

The vulnerability exists due to a type confusion error when performing certificate name checks. A remote attacker can supply a specially crafted X.509 certificate to the server, trigger a type confusion error and perform a denial of service (DoS) attack.


12) Insecure Storage of Sensitive Information (CVE-ID: CVE-2024-10041)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to software stores secrets in memory in plain text. A local user can read the memory and obtain passwords in plain text when PAM is used to perform authentication.


13) Improper authentication (CVE-ID: CVE-2024-10963)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in pam_access module where certain rules in its configuration file are mistakenly treated as hostnames. A remote attacker can bypass authentication process and gain unauthorized access to the system.


14) Use-after-free (CVE-ID: CVE-2024-25062)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in xmlValidatePopElement when using the XML Reader interface with DTD validation and XInclude expansion enabled. A remote attacker can pass a specially crafted XML document to the application, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


15) Input validation error (CVE-ID: CVE-2024-28182)

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

The vulnerability exists due to reading the unbounded number of HTTP/2 CONTINUATION frames. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


16) Cryptographic issues (CVE-ID: CVE-2024-28834)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to a side-channel attack when using the gnutls_privkey_sign_data2 API function with the "GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE" flag. A remote attacker can launch Minerva attack and gain access to sensitive information.


17) Input validation error (CVE-ID: CVE-2024-28835)

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

The vulnerability exists due to insufficient validation of user-supplied input when parsing the cert_list_size parameter in the gnutls_x509_trust_list_verify_crt2() function in certtool. A remote attacker can pass specially crafted PEM encoded certificate chain that contains more than 16 certificates to the certtool and crash it.


18) Insufficient verification of data authenticity (CVE-ID: CVE-2024-34397)

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

The vulnerability exists due to missing authorization for D-Bus signals. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service.
