CVE-2026-57198 1 Asterisk 2 Asterisk, Certified Asterisk 2026-10-27 N/A
Asterisk is an open source private branch exchange and telephony toolkit. In affected deployments, an authenticated attacker may cause a `T.140 RED` heap buffer overflow using carefully crafted packets, potentially allowing remote code execution or causing Asterisk to crash. The `chan_sip` channel driver must be installed and configured, and its `textsupport` option must be enabled; `textsupport` defaults to no. `The chan_sip driver was deprecated in Asterisk 20 and completely removed in all later versions.` Repository comparisons verify patch containment in Asterisk 20.20.1, 21.12.3, 22.10.1 and 23.4.1, and Certified Asterisk 20.7-cert11 and 22.8-cert3. The affected release-track scope remains unresolved: structured metadata includes later release tracks even though the advisory says the required `chan_sip` driver was removed there.
CVE-2026-116647 1 Tanium 1 Comply 2026-10-27 7.1 High
Tanium addressed an improper output sanitization vulnerability in Comply.
CVE-2026-116649 1 Tanium 1 Enforce 2026-10-27 7.1 High

CVE-2026-117897 1 Mozilla 1 Firefox 2026-10-27 N/A
Incorrect boundary conditions in the Layout: Tables component. This vulnerability was fixed in Firefox 159, Firefox ESR 115.44, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.
CVE-2026-109257 1 Freerdp 1 Freerdp 2026-10-27 5.9 Medium
FreeRDP before 3.32.0 contains a double-free vulnerability in nsc_context_initialize_encode() that leaves dangling plane pointers after a partial buffer growth failure. Attackers using a crafted RDP client can negotiate NSCodec with a large desktop geometry to trigger allocation failure, crashing the server during context teardown.
CVE-2026-105007 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-27 8.8 High
An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. To exploit the vulnerability, in a local attack scenario, an attacker could run a specially crafted application to elevate the attacker's privilege level. An attacker who successfully exploited this vulnerability could run processes in an elevated context. However, an attacker must first gain access to the local system with the ability to execute a malicious application in order to exploit this vulnerability. The security update addresses the vulnerability by changing how ndis.sys validates buffer length.
CVE-2026-108313 1 Tanium 1 Tanium Server 2026-10-27 6.6 Medium
Tanium addressed an incorrect privilege assignment vulnerability in Tanium Server.
CVE-2026-117993 1 Mozilla 1 Firefox 2026-10-27 N/A
Integer overflow in the Graphics: Text component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.
CVE-2026-110247 1 Mozilla 1 Thunderbird 2026-10-27 8.4 High
Several buffer-growth sites in libmime performed size arithmetic in 32-bit types without overflow checks. On a sufficiently large message the growth guard could fail open, or the buffer could be reallocated smaller than required, and a subsequent memcpy would then write attacker-controlled data across adjacent heap allocations. This vulnerability was fixed in Thunderbird 158 and Thunderbird 153.6.
CVE-2026-109089 1 X.org 1 Libxi 2026-10-27 7.5 High
A buffer overflow when handling DEVICE_RESOLUTION in libXi before 1.8.4 could overflow a heap, triggered by a malicious X server.
CVE-2026-116469 1 Misp 1 Misp-guard 2026-10-27 N/A
MISP Guard, a proxy-based security filter for MISP feed distribution, contains a case-sensitivity flaw in multiple policy enforcement checks. The functions check_required_taxonomy_exists, check_required_taxonomy_tags_allowed, check_blocked_attribute_categories, and check_blocked_analyst_data_sharing_groups_uuids performed case-sensitive string comparisons when matching event tags, attribute categories, and sharing-group UUIDs against configured allow/block lists. An attacker with the ability to create or modify events in a MISP instance (or a connected instance that pushes events through the guard) could craft events using different letter case in taxonomy tag names, attribute categories, or sharing-group UUIDs to bypass the configured security policies. For example, if the policy requires the 'tlp' taxonomy with only 'tlp:clear' allowed, an event tagged 'TLP:AMBER' would not be recognized as belonging to the 'tlp' taxonomy and would therefore not be checked against the allowed-tags list, resulting in the event being forwarded to feed consumers. Similarly, a blocked attribute category such as 'Person' would not match a configured block entry of 'person', allowing the attribute to pass through the filter. The security impact is unauthorized disclosure of threat-intelligence data that the operator intended to restrict. Events carrying non-allowed TLP (Traffic Light Protocol) markings, blocked attribute categories, or blocked sharing-group associations are forwarded to downstream feed consumers in violation of the configured distribution policy. This undermines the confidentiality controls that MISP Guard is designed to enforce. The vulnerability is trivially exploitable: the attacker only needs to alter the letter case of a tag, category, or UUID string. No authentication beyond normal MISP event-creation privileges is required, and no user interaction is needed.
CVE-2026-57197 1 Asterisk 2 Asterisk, Certified Asterisk 2026-10-27 N/A
Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an unbounded `memcpy` of `OGG/Speex` packet data in `format_ogg_speex` can cause a heap buffer overflow and crash Asterisk when reading a file containing corrupted Speex audio. The attacker must create the file and make it available to Asterisk either through sufficiently elevated privileges or by convincing an Asterisk administrator to make it available. Asterisk must also be configured to play that file. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.
CVE-2026-92372 1 Teamviewer 1 Full Client 2026-10-27 8.8 High
An out-of-bounds write vulnerability in the screen-image decoder of TeamViewer Full Client for Linux and macOS prior to version 15.83 allows a remote attacker to execute arbitrary code by supplying crafted screen-image data during a remote-control session. The vulnerability can also be exploited by persuading a user to open a specially crafted TeamViewer session recording (.tvs). Missing destination bounds checking in the decoder allows crafted screen-image data to cause an out-of-bounds write to the image buffer. Exploitation requires user interaction.
CVE-2026-88812 1 X.org 3 Xorg-server, Xorg-x11-server, Xwayland 2026-10-27 7.8 High
A double free in XKB SetGeometryin X.Org X Server before 21.1.25 and X Wayland before 24.1.14 could be used by attached clients to cause a crash or potentially code in the x server context.
