  - managed-keys is a feature which allows a BIND resolver to automatically maintain the keys used by trust     anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys     feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if,     during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm.
    Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions     9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13     development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for     vulnerability to CVE-2018-5745. (CVE-2018-5745)

  - Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones     are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and     versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13     development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for     vulnerability to CVE-2019-6465. (CVE-2019-6465)

  - With pipelining enabled each incoming query on a TCP connection requires a similar resource allocation to     a query received via UDP or via TCP without pipelining enabled. A client using a TCP-pipelined connection     to a server could consume more resources than the server has been provisioned to handle. When a TCP     connection with a large number of pipelined queries is closed, the load on the server releasing these     multiple resources can cause it to become unresponsive, even for queries that can be answered     authoritatively or from cache. (This is most likely to be perceived as an intermittent server problem).

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1016 advisory.

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to     the current task's default request-key keyring via the request_key() system call, allowing a local user     to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write     permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
    (CVE-2017-17807)

  - The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num     from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds     (OOB) read that potentially allows arbitrary read in the kernel address space. (CVE-2018-19985)

  - An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during     the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
    (CVE-2018-20169)

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343. (CVE-2018-7191)

  - A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before     4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware     could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.
    (CVE-2019-10207)

  - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page     that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)

  - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel     image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the     attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic     is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a network namespace. (CVE-2019-10639)

  - The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because     install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the     ptrace_may_access() check has a race condition when reading /proc/pid/stat. (CVE-2019-11190)

  - The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a     local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command,     because a name field may not end with a '\0' character. (CVE-2019-11884)

  - An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL     pointer dereference (CVE-2019-12382)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled,     a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn()     system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c. (CVE-2019-13648)

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell     wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or     possibly execute arbitrary code. (CVE-2019-14814)

  - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params()     function of Marvell Wifi Driver. (CVE-2019-14815)

  - An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the Linux kernel before 5.1.12. In the     qedi_dbg_* family of functions, there is an out-of-bounds read. (CVE-2019-15090)

  - An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound     subsystem because card disconnection causes certain data structures to be deleted too early. This is     related to sound/core/init.c and sound/core/info.c. (CVE-2019-15214)

  - An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a     malicious USB device in the sound/usb/line6/pcm.c driver. (CVE-2019-15221)

  - An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check     the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it     is possible for the specified target task to perform an execve() syscall with setuid execution before     perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check     and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged     execve() calls. This issue affects kernel versions before 4.8. (CVE-2019-3901)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

  - An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap     overflow in the parser for AIX log messages. The parser tries to locate a log message delimiter (in this     case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the     string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check     that detects invalid log messages. The message will then be considered valid, and the parser will eat up     the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was     zero and now becomes minus one. The following step in the parser is to shift left the contents of the     message. To do this, it will call memmove with the right pointers to the target and destination strings,     but the lenMsg will now be interpreted as a huge value, causing a heap overflow. (CVE-2019-17041)

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.

  - When deriving an identifier for an email message, uninitialized memory was used in addition to the message     contents. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6792)

  - When processing an email message with an ill-formed envelope, Thunderbird could read data from a random     memory location. This vulnerability affects Thunderbird < 68.5. (CVE-2020-6793)

  - If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy     of these passwords is still accessible. This is because the older stored password file was not deleted     when the data was copied to a new format starting in Thunderbird 60. The new master password is added only     on the new file. This could allow the exposure of stored password data outside of user expectations. This     vulnerability affects Thunderbird < 68.5. (CVE-2020-6794)

  - When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code     caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects     Thunderbird < 68.5. (CVE-2020-6795)

  - If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and     execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer     a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email     in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in     browser or browser-like contexts.
