CVE-2025-54572 Ruby SAML DOS vulnerability with large SAML response

The Ruby SAML library is for implementing the client side of a SAML authorization. In versions 1.18.0 and below, a denial-of-service vulnerability exists in ruby-saml even with the messagemaxbytesize setting configured. The vulnerability occurs because the SAML response is validated for Base64...

BadReward: Clean-Label Poisoning of Reward Models in Text-To-Image RLHF

Reinforcement Learning from Human Feedback RLHF is crucial for aligning text-to-image T2I models with human preferences. However, RLHF's feedback mechanism also opens new pathways for adversaries. This paper demonstrates the feasibility of hijacking T2I models by poisoning a small fraction of...

The Planted Orthogonal Vectors Problem

In the $k$-Orthogonal Vectors $k$-OV problem we are given $k$ sets, each containing $n$ binary vectors of dimension $d=n^o1$, and our goal is to pick one vector from each set so that at each coordinate at least one vector has a zero. It is a central problem in fine-grained complexity, conjectured...

WinSCP < 6.3.3 Key Recovery Attack Vulnerability

The version of WinSCP installed on the remote Windows host is prior to 6.3.3. It is, therefore, affected by a key recovery attack vulnerability. In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in...

FreeBSD : PuTTY and embedders (f.i., filezilla) -- biased RNG with NIST P521/ecdsa-sha2-nistp521 signatures permits recovering private key (080936ba-fbb7-11ee-abc8-6960f2492b1d)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 080936ba-fbb7-11ee-abc8-6960f2492b1d advisory. - In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a...

CVE-2024-31497

In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is especially important in a scenario where an adversary is able to read messages signed by PuTTY or Pageant...

PuTTY 安全漏洞

PuTTY is a suite of free Telnet, Rlogin, and SSH client software from the individual developer Simon Tatham. The software is primarily used for remote administration of Linux systems. A security vulnerability exists in PuTTY versions 0.68 through 0.80, which stems from the presence of biased rand...

PuTTY and embedders (f.i., filezilla) -- biased RNG with NIST P521/ecdsa-sha2-nistp521 signatures permits recovering private key

Simon Tatham reports: ECDSA signatures using 521-bit keys the NIST P521 curve, otherwise known as ecdsa-sha2-nistp521 were generated with biased random numbers. This permits an attacker in possession of a few dozen signatures to RECOVER THE PRIVATE KEY. Any 521-bit ECDSA private key that PuTTY or...

Awful 4chan chat bot spouts racial slurs and antisemitic abuse

“A robot may not injure a human being or, through inaction, allow a human being to come to harm” Science fiction readers, and many others, will recognize Asimov’s first law of robotics. After reading about a bot called GPT-4chan I was wondering whether we should include: “A bot may not insult a...
