CVE-2017-7781/CVE-2017-10176: Issue with elliptic curve addition in mixed Jacobian-affine coordinates in Firefox/Java

tl;dr Firefox and Java suffered from a moderate vulnerability affecting the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result POINTATINFINITY when it should not. Introduction Few months ago I was working on a vulnerability affecting th...

CVE-2017-7781

An error occurs in the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result "POINTATINFINITY" when it should not. A man-in-the-middle attacker could use this to interfere with a connection, resulting in an attacked party computing an...

kernel: crypto: GPF in lrw_crypt caused by null-deref

The lrwcrypt function in 'crypto/lrw.c' in the Linux kernel before 4.5 allows local users to cause a system crash and a denial of service by the NULL pointer dereference via accept2 system call for AFALG socket without calling setkey first to set a cipher key...

Uber Drivers Hacking the System to Cause Surge Pricing

Interesting story about Uber drivers who have figured out how to game the company's algorithms to cause surge pricing: According to the study. drivers manipulate Uber's algorithm by logging out of the app at the same time, making it think that there is a shortage of cars. ... The study said drive...

PT-2017-17940

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 55 Description An error in the elliptic curve point addition algorithm can yield an incorrect result, potentially allowing a man-in-the-middle attacker to interfere with a connection and cause the attacked party to...

KLA11082 Multiple vulnerabilities in Mozilla Firefox and Firefox ESR

Multiple serious vulnerabilities have been found in Firefox and Firefox ESR. Malicious users can exploit these vulnerabilities to cause denial of service, privilege escalation, spoof user interface, bypass security restrictions, obtain sensitive information and execute arbitrary code. Below is...

OpenJDK: DSA implementation timing attack (JCE, 8175106)

A covert timing channel flaw was found in the DSA implementation in the JCE component of OpenJDK. A remote attacker able to make a Java application generate DSA signatures on demand could possibly use this flaw to extract certain information about the used key via a timing side channel...

Hacking Slot Machines by Reverse-Engineering the Random Number Generators

Interesting story: The venture is built on Alex's talent for reverse engineering the algorithms -- known as pseudorandom number generators, or PRNGs -- that govern how slot machine games behave. Armed with this knowledge, he can predict when certain games are likeliest to spit out money­insight...

CVE-2017-9859

An issue was discovered in SMA Solar Technology products. The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This...

CVE-2017-9859

CVE-2017-9859 concerns SMA Solar Technology inverters (Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30). The issue is use of a weak hashing algorithm to encrypt passwords for REGISTER requests, which can be cracked offline, enabling an attacker to recover the password and register at SMA s...

CVE-2017-9859

An issue was discovered in SMA Solar Technology products. The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This...

CVE-2017-9856

An issue was discovered in SMA Solar Technology products. Sniffed passwords from SMAdata2+ communication can be decrypted very easily. The passwords are "encrypted" using a very simple encryption algorithm. This enables an attacker to find the plaintext passwords and authenticate to the device...

CVE-2017-9859: Use of a Broken or Risky Cryptographic Algorithm
