CVE-2020-15679 (severity: HIGH, weakness: CWE-384)
An OAuth session fixation vulnerability existed in the VPN login flow, where an attacker could craft a custom login URL, convince a VPN user to login via that URL, and obtain authenticated access as that user. This issue is limited to cases where attacker and victim are sharing the same source IP and could allow the ability to view session states and disconnect VPN sessions. This vulnerability affects Mozilla VPN iOS 1.0.7 < (929), Mozilla VPN Windows < 1.2.2, and Mozilla VPN Android 1.1.0 < (1360).
CVE-2020-1568 (severity: HIGH, weakness: NVD-CWE-Other)
A remote code execution vulnerability exists when Microsoft Edge PDF Reader improperly handles objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit the vulnerability, in a web-based attack scenario, an attacker could host a website that contains malicious PDF content. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted PDF content that could exploit the vulnerability. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could trick a user into clicking a link that takes the user to the attacker's site. The security update addresses the vulnerability by modifying how Microsoft Edge PDF Reader handles objects in memory.
CVE-2020-15680 (severity: MEDIUM, weakness: NVD-CWE-Other)
If a valid external protocol handler was referenced in an image tag, the resulting broken image size could be distinguished from a broken image size of a non-existent protocol handler. This allowed an attacker to successfully probe whether an external protocol handler was registered. This vulnerability affects Firefox < 82.
CVE-2020-15681 (severity: HIGH, weakness: NVD-CWE-Other)
When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM thread could have overwritten another's entry in a shared stub table, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 82.
CVE-2020-15682 (severity: MEDIUM, weakness: CWE-346)
When a link to an external protocol was clicked, a prompt was presented that allowed the user to choose what application to open it in. An attacker could induce that prompt to be associated with an origin they didn't control, resulting in a spoofing attack. This was fixed by changing external protocol prompts to be tab-modal while also ensuring they could not be incorrectly associated with a different origin. This vulnerability affects Firefox < 82.
CVE-2020-15683 (severity: CRITICAL, weakness: CWE-416)
Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3.

CVE-2020-15687 (severity: HIGH, weakness: NVD-CWE-Other)
Missing access control restrictions in the Hypervisor component of the ACRN Project (v2.0 and v1.6.1) allow a malicious entity, with root access in the Service VM userspace, to abuse the PCIe assign/de-assign Hypercalls via crafted ioctls and payloads. This attack results in a corrupt state and Denial of Service (DoS) for previously assigned PCIe devices to the Service VM at runtime.
CVE-2020-15688 (severity: HIGH, weakness: CWE-294)
The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel.
CVE-2020-15689 (severity: HIGH, weakness: CWE-476)
Appweb before 7.2.2 and 8.x before 8.1.0, when built with CGI support, mishandles an HTTP request with a Range header that lacks an exact range. This may result in a NULL pointer dereference and cause a denial of service.
CVE-2020-1569 (severity: HIGH, weakness: CWE-787)
A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by way of enticement in an email or Instant Messenger message, or by getting them to open an attachment sent through email. The security update addresses the vulnerability by modifying how Microsoft Edge handles objects in memory.
CVE-2020-15690 (severity: CRITICAL, weakness: CWE-74)
In Nim before 1.2.6, the standard library asyncftpclient lacks a check for whether a message contains a newline character.

CVE-2020-1570 (severity: HIGH, weakness: CWE-787)
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked &quot;safe for initialization&quot; in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability. The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory.
CVE-2020-15700 (severity: MEDIUM, weakness: CWE-352)
An issue was discovered in Joomla! through 3.9.19. A missing token check in the ajax_install endpoint of com_installer causes a CSRF vulnerability.
CVE-2020-15701 (severity: MEDIUM, weakness: CWE-755)
An unhandled exception in check_ignored() in apport/report.py can be exploited by a local attacker to cause a denial of service. If the mtime attribute is a string value in apport-ignore.xml, it will trigger an unhandled exception, resulting in a crash. Fixed in 2.20.1-0ubuntu2.24, 2.20.9-0ubuntu7.16, 2.20.11-0ubuntu27.6.
CVE-2020-15702 (severity: HIGH, weakness: CWE-367)
TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate privileges. Fixed in 2.20.1-0ubuntu2.24, 2.20.9 versions prior to 2.20.9-0ubuntu7.16 and 2.20.11 versions prior to 2.20.11-0ubuntu27.6. Was ZDI-CAN-11234.
CVE-2020-15703 (severity: LOW, weakness: CWE-22)
There is no input validation on the Locale property in an apt transaction. An unprivileged user can supply a full path to a writable directory, which lets aptd read a file as root. Having a symlink in place results in an error message if the file exists, and no error otherwise. This way an unprivileged user can check for the existence of any files on the system as root.
CVE-2020-15704 (severity: MEDIUM, weakness: CWE-200)
The modprobe child process in the ./debian/patches/load_ppp_generic_if_needed patch file incorrectly handled module loading.
