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...

Private CRT-based RSA Key Leakage

crypto/rsa in github.com/golang/go is vulnerable to private CRT-based RSA key leakage. The leakage happens due to an error in the CRT computation. And it fails to check RSA signature to prevent the error...

UBUNTU-CVE-2017-6076

In versions of wolfSSL before 3.10.2 the function fpmulcomba makes it easier to extract RSA key information for a malicious user who has access to view cache on a machine...

USN-3181-1 openssl vulnerabilities

Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as other releases were...

openssl: Non-constant time codepath followed for certain operations in DSA implementation

It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm DSA signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system...

UBUNTU-CVE-2016-10011

authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process...

Debian DLA-762-1 : exim4 security update

Bjoern Jacke discovered that Exim, Debian's default mail transfer agent, may leak the private DKIM signing key to the log files if specific configuration options are met. For Debian 7 'Wheezy', these problems have been fixed in version 4.80-7+deb7u4. We recommend that you upgrade your exim4...

FreeBSD : go -- information disclosure vulnerability (6809c6db-bdeb-11e5-b5fe-002590263bf5)

Jason Buberel reports : A security-related issue has been reported in Go's math/big package. The issue was introduced in Go 1.5. We recommend that all users upgrade to Go 1.5.3, which fixes the issue. Go programs must be recompiled with Go 1.5.3 in order to receive the fix. The Go team would like...

DEBIAN-CVE-2015-3193

The Montgomery squaring implementation in crypto/bn/asm/x8664-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x8664 platform, as used by the BNmodexp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key...

UBUNTU-CVE-2015-2141

The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack...

PT-2016-1330 · Openssl +6 · Openssl +7

Name of the Vulnerable Software and Affected Versions: OpenSSL versions prior to 0.9.8zf OpenSSL versions prior to 1.0.0r OpenSSL versions prior to 1.0.1m OpenSSL versions prior to 1.0.2a Description: The issue allows man-in-the-middle attackers to determine the MASTER-KEY value and decrypt TLS...

Parallels Plesk Panel 12.x Key Disclosure

While auditing the source code for Parallels Plesk Panel 12.x on Linux I noticed the following feature that leads to leakage of the '/etc/psa/private/secretkey'-file in md5 format to non-authenticated users. Parallels responded that the 16byte 'secretkey' should provide sufficient entropy for thi...

Stunnel PRING初始化漏洞

Bugtraq ID:65964 CVE ID:CVE-2014-0016 Stunnel是一个自由的跨平台软件，用于提供全局的TLS / SSL 服务。 Stunnel存在安全漏洞，套接字封装程序可对普通应用程序提供SSL支持，在fork后执行PRNG初始化，当接受新连接时，服务器fork，子进程处理请求。OpenSSLRANDbytes函数在fork后没有重置其状态，而是简单的添加当前进程IDgetpid至PRNG状态，可导致使用EC ECDSA或DSA证书的服务器在某些情况下泄漏私钥。 0 Stunnel 目前没有详细解决方案提供： http://www.stunnel.org...
