Security Fix(es):
edk2: A flaw was found in the EDK2 package. This flaw allows an attacker to cause memory corruption due to an overflow via an adjacent network. This issue may lead to loss of confidentiality, integrity, and availability.(CVE-2024-38796)
edk2: A security weakness was identified in EDK2, the open-source reference implementation of the UEFI specification, revealing a buffer overflow vulnerability. This vulnerability enables an unauthorized attacker within proximity on the network to transmit a specifically crafted DHCPv6 Advertise message. As a consequence, it results in the unauthorized disclosure of information and jeopardizes the availability of the system.(CVE-2023-45234)
edk2: A divide-by-zero vulnerability was found in edk2. A successful exploit of this vulnerability may lead to a loss of availability.(CVE-2024-1298)
edk2: A flaw was found in edk2. A integer underflow in the SmmEntryPoint function leads to a write into the SMM region allowing a local attacker with administration privileges on the system to execute code within the SMM privileged context. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2021-38578)
edk2: A flaw was found in OpenSSL resulting in a possible denial of service while translating ASN.1 object identifiers. Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience long delays when processing messages, which may lead to a denial of service.(CVE-2023-2650)
edk2: A security flaw has been identified in the cryptographic system of EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized remote attacker to potentially expose sensitive information.(CVE-2023-45237)
edk2: A security flaw has been identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker to potentially disclose sensitive information.(CVE-2023-45236)
edk2: A heap-based buffer overflow flaw was found via the Tcg2MeasurePeImage() function in EDK2. Successful exploitation requires a local attacker to trigger an integer overflow in the calculation of the EventSize variable at DxeTpm2MeasureBootLib.c, leading to the heap-buffer overflow, presenting a moderate risk to confidentiality and integrity. However, the primary consequence is likely a crash or denial of service.(CVE-2022-36764)
edk2: A flaw was found in the CreateHob() function in EDK2. An attacker, leveraging a local network, can initiate an integer overflow leading to a buffer overflow. This issue arises during size alignment within the CreateHob() function, requiring activation in the PEI phase. Successful exploitation of this flaw poses a moderate threat to confidentiality and integrity, however, the primary consequence is likely a crash or denial of service.(CVE-2022-36765)
edk2: The Network Package in EDK2 is vulnerable to an infinite loop exploit when parsing a PadN option within the Destination Options header of IPv6. This flaw allows an unauthorized attacker to gain access and potentially result in a loss of system availability.(CVE-2023-45233)
edk2: A heap buffer overflow flaw was found via the Tcg2MeasureGptTable() function in EDK2, arising from inadequate validation of the GPT Primary Header, presenting a minor risk to confidentiality and integrity. The primary consequence is likely a crash or denial of service. This issue may allow a local attacker to craft a GPT table, causing an integer overflow and consequent buffer overflow.(CVE-2022-36763)
edk2: A security loophole involving an out-of-bounds read was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted Neighbor Discovery Redirect message. Consequently, this may lead to the unauthorized reading of memory beyond the message boundaries, potentially resulting in the exposure of sensitive information.(CVE-2023-45231)
edk2: A security loophole involving an infinite loop was identified in EDK2, the open-source reference implementation of the UEFI specification. This weakness enables an unauthorized attacker to exploit system availability by sending a specifically crafted Destination Options IPv6 header.(CVE-2023-45232)
edk2: A vulnerability was found in OpenSSL. This security flaw occurs because the applications that use the DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source may lead to a denial of service.(CVE-2023-3446)
edk2: Real Time Automation 460 Series products with versions prior to v8.9.8 are vulnerable to cross-site scripting, which could allow an attacker to run any JavaScript reference from the URL string. If this were to occur, the gateway's HTTP interface would redirect to the main page, which is index.htm. (CVE-2023-4523)
edk2: A vulnerability has been identified in the NetworkPkg IP stack of EDK2, the open-source reference implementation of the UEFI specification. This flaw enables an unauthenticated attacker within the same network vicinity to transmit a specifically crafted DHCPv6 message. Exploiting this vulnerability may result in unauthorized access to memory beyond its boundaries, potentially leading to the exposure of sensitive information.(CVE-2023-45229)
edk2: A security flaw was identified in EDK2, the open-source reference implementation of the UEFI specification, involving a buffer overflow vulnerability. This particular weakness enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted DHCPv6 message. This, in turn, could result in an information disclosure and compromise the availability of the system.(CVE-2023-45230)
edk2: A security flaw involving buffer overflow was identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker within the vicinity network to transmit a specifically crafted DHCPv6 proxy Advertise message, resulting in the disclosure of information and potential compromise of system availability.(CVE-2023-45235)
edk2: bugfix
bind: A flaw was found in the bind9 package, where a hostname with significant resource records may slow down bind's resolver cache and authoritative zone databases while these records are being added or updated. In addition, client queries for the related hostname may cause the same issue. This vulnerability may lead to a denial of service.(CVE-2024-1737)
bind: A logic error was found in the io_uring subsystem of the Linux kernel. This issue occurs due to an incorrect assumption that the last io_grab_identity call could not return false in the io_prep_async_work function, leading to reference counting issues and a use-after-free issue. This could allow a local user to crash or escalate their privileges on the system.(CVE-2023-0240)
bind: bugfix
