Description
This security bulletin contains information about 21 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-39326)
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 handling HTTP chunked requests. A remote attacker can send specially crafted HTTP requests to the server and consume excessive memory resources.
2) Resource exhaustion (CVE-ID: CVE-2023-45288)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.3) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
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) Improper Authentication (CVE-ID: CVE-2023-2975)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in the AES-SIV cipher implementation when authenticating empty data entries via the EVP_EncryptUpdate() and EVP_CipherUpdate() functions. A remote attacker can bypass authentication process and impact application's integrity.
6) Use-after-free (CVE-ID: CVE-2023-3019)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the e1000e_write_packet_to_guest() function in the e1000e NIC emulation code in QEMU. A local user can trigger DMA reentrancy and crash the QEMU process on the host.
7) Infinite loop (CVE-ID: CVE-2023-3255)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the vnc_client_cut_text_ext function in ui/vnc-clipboard.c. A remote authenticated client who is able to send a clipboard to the QEMU built-in VNC server can perform a denial of service conditions.
8) Resource management error (CVE-ID: CVE-2023-3446)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) Resource management error (CVE-ID: CVE-2023-3817)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
10) Improper synchronization (CVE-ID: CVE-2023-5088)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper synchronization, which causes guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead. An L2 guest with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor can read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
11) Resource management error (CVE-ID: CVE-2023-5678)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
12) State Issues (CVE-ID: CVE-2023-6129)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in POLY1305 MAC (message authentication code) implementation on PowerPC CPU based platforms if the CPU provides vector instructions. A remote attacker can perform a denial of service (DoS) attack.
13) Resource management error (CVE-ID: CVE-2023-6237)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way the EVP_PKEY_public_check() function handles RSA public keys. A remote attacker can supply an RSA key obtained from an untrusted source and perform a denial of service (DoS) attack.
14) NULL pointer dereference (CVE-ID: CVE-2023-6683)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing ClientCutText messages within the QEMU built-in VNC server. A remote authenticated VNC client can pass specially crafted data to the application and perform a denial of service (DoS) attack.
15) Insufficient verification of data authenticity (CVE-ID: CVE-2023-7008)
The vulnerability allows a remote attacker to perform a MitM attack.
The vulnerability exists due to systemd-resolved accepts records of DNSSEC-signed domains even when they have no signature. A remote attacker can perform MitM attack.
16) 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.
17) Division by zero (CVE-ID: CVE-2023-42467)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to a division by zero error within the scsi_disk_reset() function in hw/scsi/scsi-disk.c. A local user can pass specially crafted data to the application and crash it.
18) NULL pointer dereference (CVE-ID: CVE-2024-0727)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when processing fields in the PKCS12 certificate. A remote attacker can pass specially crafted certificate to the server and perform a denial of service (DoS) attack.
19) 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.
20) 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.
21) 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.
