important: kernel/thunderbird security update
important
An update for kernel/thunderbird is now available for NewStart CGSL MAIN 5.05/CGSL CORE 5.05.
NewStart Security has rated this update as having a security impact of important. A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
kernel: The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc. This variant of the kernel has numerous debugging options enabled. It should only be installed when trying to gather additional information on kernel bugs, as some of these options impact performance noticably.
thunderbird: Mozilla Thunderbird is a standalone mail and newsgroup client.
Security Fix(es):
kernel: The iscsi_if_rx() function in 'drivers/scsi/scsi_transport_iscsi.c' in the Linux kernel from v2.6.24-rc1 through 4.13.2 allows local users to cause a denial of service (a system panic) by making a number of certain syscalls by leveraging incorrect length validation in the kernel code.(CVE-2017-14489)
kernel: A vulnerability was found in hiddev_open in drivers/hid/usbhid/hiddev.c in the USB Human Interface Device class subsystem, where an existing device must be validated prior to its access. The device should also ensure the hiddev_list cleanup occurs at failure, as this may lead to a use-after-free problem, or possibly escalate privileges to an unauthorized user.(CVE-2019-19527)
kernel: A flaw was found in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.(CVE-2020-10757)
kernel: A flaw was found in the way the mwifiex_cmd_append_vsie_tlv() in Linux kernel's Marvell WiFi-Ex driver handled vendor specific information elements. A local user could use this flaw to escalate their privileges on the system.(CVE-2020-12653)
kernel: A flaw was found in the Linux kernel. The Marvell mwifiex driver allows a remote WiFi access point to trigger a heap-based memory buffer overflow due to an incorrect memcpy operation. The highest threat from this vulnerability is to data integrity and system availability.(CVE-2020-12654)
kernel: A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the read/write devices' MMIO address space when it is disabled, some h/w devices issue an interrupt to the CPU to indicate a fatal error condition, crashing the system. This flaw allows a guest user or process to crash the host system resulting in a denial of service.(CVE-2020-12888)
kernel: bugfix
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers reported memory safety bugs present in Firefox 76 and Firefox ESR 68.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.(CVE-2020-12410)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.(CVE-2020-12406)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash.(CVE-2020-12405)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection.(CVE-2020-12398)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier, resulting in memory corruption and a potentially exploitable crash.(CVE-2020-12417)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript.(CVE-2020-12418)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free condition. This could have led to memory corruption and a potentially exploitable crash.(CVE-2020-12419)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash.(CVE-2020-12420)
thunderbird: The Mozilla Foundation Security Advisory describes this flaw as: When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user.(CVE-2020-12421)
thunderbird: Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.(CVE-2020-6463)
thunderbird: Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream.(CVE-2020-6514)
thunderbird: By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.(CVE-2020-15652)
thunderbird: Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.(CVE-2020-15659)
thunderbird: If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird sends username and password over https to a server controlled by the attacker. This vulnerability affects Thunderbird < 68.10.0.(CVE-2020-15646)
