Description
This security bulletin contains information about 18 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-4004)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. A local user can execute arbitrary code with elevated privileges.
2) 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.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-34969)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in the dbus-daemon when sending a reply message from the "bus driver". If a local privileged user (e.g. root) is using the org.freedesktop.DBus.Monitoring interface to monitor message bus traffic, another unprivileged user with the ability to connect to the same dbus-daemon can force the service to send an unreplyable message and perform a denial of service (DoS) attack.
4) Use-after-free (CVE-ID: CVE-2023-31248)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in nft_chain_lookup_byid() function, which failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace. A local user ca trigger a use-after-free error and execute arbitrary code with elevated privileges.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-30630)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions when executing the command with the "--dump-bin" option. A local user can overwrite arbitrary files on the system and escalate privileges.
6) Security features bypass (CVE-ID: CVE-2023-21102)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists die to a logic error within the __efi_rt_asm_wrapper() function in efi-rt-wrapper.S. A local application can bypass the shadow stack protection and execute arbitrary code with elevated privileges.
7) Use-after-free (CVE-ID: CVE-2023-20593)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in AMD Zen2 processors. A local user can trigger a use-after-free error and execute arbitrary code on the system.
Note, the vulnerability was dubbed Zenbleed.
8) Use-after-free (CVE-ID: CVE-2023-4147)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
9) Incorrect authorization (CVE-ID: CVE-2023-3899)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect authorization caused by D-Bus interface com.redhat.RHSM1 that exposes a significant number of methods to all users. A local user can abuse the com.redhat.RHSM1.Config.SetAll() method to change the state of the registration and escalate privileges on the system.
10) Resource exhaustion (CVE-ID: CVE-2022-41723)
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 in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
11) 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.
12) Use-after-free (CVE-ID: CVE-2023-3610)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the nf_tables component in Linux kernel netfilter. A local user with CAP_NET_ADMIN capability can trigger a use-after-free error and execute arbitrary code with elevated privileges.
13) Use-after-free (CVE-ID: CVE-2023-3390)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within net/netfilter/nf_tables_api.c in the Linux kernel netfilter subsystem. A local user can trigger a use-after-fee error and escalate privileges on the system.
14) NULL pointer dereference (CVE-ID: CVE-2023-3354)
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 the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in NULL pointer dereference and denial of service.
15) 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.
16) 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.
17) Information exposure through microarchitectural state after transient execution (CVE-ID: CVE-2023-1637)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due speculative execution behavior in the Linux kernel X86 CPU Power management options functionality. A local user can gain access to sensitive information.
18) Cross-site scripting (CVE-ID: CVE-2016-3709)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
