CVE-2019-11745

CVE-2019-11745 is a heap-based out-of-bounds write in Mozilla NSS (NSC_EncryptUpdate) when data smaller than the block size is encrypted. This could allow a remote attacker to trigger a crash or execute arbitrary code with the user’s privileges (attack surface includes NSS-enabled apps such as Th...

Security Vulnerabilities fixed in - Firefox 71 — Mozilla

Improper refcounting of soft token session objects could cause a use-after-free and crash likely limited to a denial of service. When using nested workers, a use-after-free could occur during worker destruction. This resulted in a potentially exploitable crash. When setting a thread name on Windo...

Security Vulnerabilities fixed in - Thunderbird 68.3 — Mozilla

When using nested workers, a use-after-free could occur during worker destruction. This resulted in a potentially exploitable crash. When setting a thread name on Windows in WebRTC, an incorrect number of arguments could have been supplied, leading to stack corruption and a potentially exploitabl...

OpenVPN Encryption Block

The vulnerability of the OpenVPN software is related to issues with encryption when using a 64-bit block cipher. Exploiting this vulnerability allows a malicious actor to restore the original message through a “Sweet32” attack...

CVE-2019-11745

When encrypting with a block cipher, if a call to NSCEncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird 68.3, Firefox ESR 68.3, an...

Donut - Generates X86, X64, Or AMD64+x86 Position-Independent Shellcode That Loads .NET Assemblies, PE Files, And Other Windows Payloads From Memory

Donut generates x86 or x64 shellcode from VBScript, JScript, EXE, DLL including .NET Assemblies files. This shellcode can be injected into an arbitrary Windows processes for in-memory execution. Given a supported file type, parameters and an entry point where applicable such as Program.Main, it...

Pwning a Siemens Scalance ICS switch through ARM reversing

We’ve been working in industrial control systems security for a long time. Several of the team here used to work in OT control rooms or support SCADA environments. Whilst pen testing a ship control system, we noticed a heavy reliance on Siemens Scalance industrial ethernet switches, so bought a...

kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service

The Salsa20 encryption algorithm in the Linux kernel, before 4.14.8, does not correctly handle zero-length inputs. This allows a local attacker the ability to use the AFALG-based skcipher interface to cause a denial of service uninitialized-memory free and kernel crash or have an unspecified othe...

LocalTapiola: Possible sweet32 lahitapiola.fi

Hello Team. I run the nmap with ssl-enum script to look for new Vulnerability that is known as "SWEET32" Detail about sweet32 vuln: Cryptographic protocols like TLS, SSH, IPsec, and OpenVPN commonly use block cipher algorithms, such as AES, Triple-DES, and Blowfish, to encrypt data between client...

Weblate: demo.weblate.org is vulnerable to SWEET32 Vulnerability

Cryptographic protocols like TLS, SSH, IPsec, and OpenVPN commonly use block cipher algorithms, such as AES, Triple-DES, and Blowfish, to encrypt data between clients and servers. To use such algorithms, the data is broken into fixed-length chunks, called blocks, and each block is encrypted...

Phabricator: Phabricator is vulnerable to padding oracle attacks and chosen-ciphertext attacks.

Dear Phabricator bug bounty team, Summary --- Phabricator encrypts data with AES in CBC mode, but does not ensure integrity of the encrypted data. You must authenticate the data, by either using an HMAC or by using an authenticated block cipher mode like GCM. Why does this vulnerability exist? --...

SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)

A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based...
