Security Fix(es):
chrony: The read_from_cmd_socket function in cmdmon.c in chronyd in Chrony before 1.23.1, and 1.24-pre1, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by sending a spoofed cmdmon packet that triggers a continuous exchange of NOHOSTACCESS messages between two daemons, a related issue to CVE-2009-3563.(CVE-2010-0292)
chrony: The client logging functionality in chronyd in Chrony before 1.23.1 does not restrict the amount of memory used for storage of client information, which allows remote attackers to cause a denial of service (memory consumption) via spoofed (1) NTP or (2) cmdmon packets.(CVE-2010-0293)
chrony: chronyd in Chrony before 1.23.1, and possibly 1.24-pre1, generates a syslog message for each unauthorized cmdmon packet, which allows remote attackers to cause a denial of service (disk consumption) via a large number of invalid packets.(CVE-2010-0294)
chrony: Multiple integer overflows in pktlength.c in Chrony before 1.29 allow remote attackers to cause a denial of service (crash) via a crafted (1) REQ_SUBNETS_ACCESSED or (2) REQ_CLIENT_ACCESSES command request to the PKL_CommandLength function or crafted (3) RPY_SUBNETS_ACCESSED, (4) RPY_CLIENT_ACCESSES, (5) RPY_CLIENT_ACCESSES_BY_INDEX, or (6) RPY_MANUAL_LIST command reply to the PKL_ReplyLength function, which triggers an out-of-bounds read or buffer overflow. NOTE: versions 1.27 and 1.28 do not require authentication to exploit.(CVE-2012-4502)
chrony: mdmon.c in Chrony before 1.29 allows remote attackers to obtain potentially sensitive information from stack memory via vectors related to (1) an invalid subnet in a RPY_SUBNETS_ACCESSED command to the handle_subnets_accessed function or (2) a RPY_CLIENT_ACCESSES command to the handle_client_accesses function when client logging is disabled, which causes uninitialized data to be included in a reply.(CVE-2012-4503)
chrony: Chrony before 1.29.1 has traffic amplification in cmdmon protocol(CVE-2014-0021)
chrony: An out-of-bounds write flaw was found in the way Chrony stored certain addresses when configuring NTP or cmdmon access. An attacker that has the command key and is allowed to access cmdmon (only localhost is allowed by default) could use this flaw to crash chronyd or, possibly, execute arbitrary code with the privileges of the chronyd process.(CVE-2015-1821)
chrony: An uninitialized pointer use flaw was found when allocating memory to save unacknowledged replies to authenticated command requests. An attacker that has the command key and is allowed to access cmdmon (only localhost is allowed by default) could use this flaw to crash chronyd or, possibly, execute arbitrary code with the privileges of the chronyd process.(CVE-2015-1822)
chrony: A denial of service flaw was found in the way chrony hosts that were peering with each other authenticated themselves before updating their internal state variables. An attacker could send packets to one peer host, which could cascade to other peers, and stop the synchronization process among the reached peers.(CVE-2015-1853)
chrony: before 1.31.2 and 2.x before 2.2.1 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."(CVE-2016-1567)
chrony: bugfix
linux-firmware: The Broadcom Wi-Fi driver in the kernel in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49G, and 6.x before 2016-02-01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted wireless control message packets, aka internal bug 25662029.(CVE-2016-0801)
linux-firmware: A remote code execution vulnerability in the Broadcom Wi-Fi firmware could enable a remote attacker to execute arbitrary code within the context of the Wi-Fi SoC. This issue is rated as Critical due to the possibility of remote code execution in the context of the Wi-Fi SoC. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-34199105. References: B-RB#110814.(CVE-2017-0561)
linux-firmware: Broadcom BCM43xx Wi-Fi chips allow remote attackers to execute arbitrary code via unspecified vectors, aka the "Broadpwn" issue.(CVE-2017-9417)
linux-firmware: bugfix
