A stack-based buffer overflow vulnerability exists in the confsrv addTimeGroup functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to a buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.

A hard-coded password vulnerability exists in the libcommonprod.so prod_change_root_passwd functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. During system startup this functionality is always called, leading to a known root password. An attacker does not have to do anything to trigger this vulnerability.

A denial of service vulnerability exists in the ucloud_del_node functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to denial of service. An attacker can send packets to trigger this vulnerability.

An information disclosure vulnerability exists in the confctl_get_guest_wlan functionality of TCL LinkHub Mesh Wifi MS1G_00_01.00_14. A specially-crafted network packet can lead to information disclosure. An attacker can send packets to trigger this vulnerability.

An out-of-bounds write vulnerability exists in the PSD Header processing memory allocation functionality of Accusoft ImageGear 20.0. A specially-crafted malformed file can lead to memory corruption. An attacker can provide a malicious file to trigger this vulnerability.

An integer overflow vulnerability exists in the way ESTsoft Alyac 2.5.8.544 parses OLE files. A specially-crafted OLE file can lead to a heap buffer overflow which can result in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

Cisco Talos today announced the release of a new mechanism that allows Cisco Secure Email customers the option to submit Sender Domain Reputation (SDR) disputes through TalosIntelligence.com. Customers now have the option of receiving self-service support through TalosIntelligence.com or may continue engaging with TAC. This new feature improves efficiency for Secure Email customers by streamlining the SDR dispute ticket process. Users can submit email sender domains and email addresses for investigation if they believe a domain or address should be marked as malicious or has been wrongfully marked as malicious. Please provide as much data as possible to assist our investigation team.

A nascent service called Dark Utilities has already attracted 3,000 users for its ability to provide command-and-control (C2) services with the goal of commandeering compromised systems. "It is marketed as a means to enable remote access, command execution, distributed denial-of-service (DDoS) attacks and cryptocurrency mining operations on infected systems," Cisco Talos said in a report shared

If you get to the Trellix Lounge, you’ve gone too far north. Our researchers will be there to answer any questions you have and present on a wide variety of security topics, from research into Adobe vulnerabilities to the privacy effects of the overtur...
