Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Improper validation of certificate with host mismatch (CVE-ID: CVE-2024-2466)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to libcurl does not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. A remote attacker force the application to completely skip the certificate check and perform MitM attack.
2) 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.
3) Improper Certificate Validation (CVE-ID: CVE-2024-2379)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper certificate validation for a QUIC connection under certain conditions, when built to use wolfSSL. A remote attacker can force the application to ignore the certificate and perform MitM attack.
Successful exploitation of the vulnerability requires that the used wolfSSL library was built with the OPENSSL_COMPATIBLE_DEFAULTS symbol set, which is not set for the recommended configure --enable-curl builds.
4) Input validation error (CVE-ID: CVE-2024-2004)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to an error when a protocol selection parameter option disables all protocols without adding any. As a result, the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols.
5) Resource exhaustion (CVE-ID: CVE-2024-22365)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in pam_namespace. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) 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.
7) 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.
8) Information disclosure (CVE-ID: CVE-2023-4641)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to an error in gpasswd(1), which fails to clean memory properly. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. A local user with enough access can retrieve the password from the memory.
9) 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.
10) XML Entity Expansion (CVE-ID: CVE-2023-52426)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to recursive XML Entity Expansion if XML_DTD is undefined at compile time. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
11) Resource exhaustion (CVE-ID: CVE-2023-52425)
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 large tokens. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
