Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Use of insufficiently random values (CVE-ID: CVE-2022-1615)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to usage of predictable random values within the GnuTLS gnutls_rnd() function. A remote user can decrypt sensitive information.
2) Use-after-free (CVE-ID: CVE-2023-3776)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the the Linux kernel's net/sched: cls_fw component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
3) Out-of-bounds write (CVE-ID: CVE-2023-35001)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the nft_byteorder() function. A local user can trigger an out-of-bounds write and execute arbitrary code on the target system.
4) State Issues (CVE-ID: CVE-2023-27536)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to cURL will reuse a previously created connection even when the GSS delegation (CURLOPT_GSSAPI_DELEGATION) option had been changed that could have changed the user's permissions in a second transfer. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, this GSS delegation setting was left out from the configuration match checks, making them match too easily, affecting krb5/kerberos/negotiate/GSSAPI transfers.
5) Input validation error (CVE-ID: CVE-2023-27533)
The vulnerability allows a remote attacker to manipulate requests.
The vulnerability exists due to missing documentation of the TELNET protocol support and the ability to pass on user name and "telnet options" for the server negotiation. A remote attacker can manipulate the connection sending unexpected data to the server via the affected client.
6) Double Free (CVE-ID: CVE-2023-27537)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when sharing HSTS data between connection. A remote attacker can initiate HSTS connection, trigger a double free error and execute arbitrary code on the target system.
7) Input validation error (CVE-ID: CVE-2023-27534)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input in the SFTP support when handling the tilde "~" character in the filepath. cURL will replace the tilde character to the current user's home directory and can reveal otherwise restricted files.
8) Information disclosure (CVE-ID: CVE-2023-27538)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.9) 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.
10) Resource management error (CVE-ID: CVE-2022-36879)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the xfrm_expand_policies() function in net/xfrm/xfrm_policy.c. A local user can cause the refcount to be dropped twice and perform a denial of service (DoS) attack.
11) Untrusted search path (CVE-ID: CVE-2023-38408)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to usage of an insecure search path within the PKCS#11 feature in ssh-agent. A remote attacker can trick the victim into connecting to a malicious SSH server and execute arbitrary code on the system, if an agent is forwarded to an attacker-controlled system.
Note, this vulnerability exists due to incomplete fix for #VU2015 (CVE-2016-10009).
12) Resource exhaustion (CVE-ID: CVE-2023-1206)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a hash collision flaw in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when an attacker makes a new kind of SYN flood attack. A remote attacker can increase the CPU usage of the server that accepts IPV6 connections up to 95%.
