New BLISTER Malware Using Code Signing Certificates to Evade Detection

Cybersecurity researchers have disclosed details of an evasive malware campaign that makes use of valid code signing certificates to sneak past security defenses and stay under the radar with the goal of deploying Cobalt Strike and BitRAT payloads on compromised systems. The binary, a loader, has...

Denial of Service in TenderMint

Description Denial of Service Tendermint 0.33.0 and above allow block proposers to include signatures for the wrong block. This may happen naturally if you start a network, have it run for some time and restart it without changing the chainID. It is a misconfiguration to reuse chainIDs. Correct...

NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS S/MIME PKCS \#7 or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS X.509 OCSP or CRL functionality may be impacted depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However email clients and PDF viewers that use NSS for signature verification such as Thunderbird LibreOffice Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.

UBUNTU-CVE-2021-45098

An issue was discovered in Suricata before 6.0.4. It is possible to bypass/evade any HTTP-based signature by faking an RST TCP packet with random TCP options of the md5header from the client side. After the three-way handshake, it's possible to inject an RST ACK with a random TCP md5header option...
