openssl: information disclosure in PKCS7_dataDecode and CMS_decrypt_set1_pkey

In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted...

Important: openssl

Issue Overview: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a grou...

Updated openssl packages fix security vulnerabilities

The updated packages fix security vulnerabilities: ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value IV should be 96 bits 12 bytes. OpenSSL allows a variable nonce length and front pads the nonce with 0...

EulerOS 2.0 SP5 : openssl110h (EulerOS-SA-2019-2218)

According to the versions of the openssl110h packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in th...

EulerOS 2.0 SP3 : openssl (EulerOS-SA-2019-2264)

According to the versions of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it...

CVE-2018-0739

Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so...

openSUSE Security Update : openssl-1_1 (openSUSE-2019-2158)

This update for openssl-11 fixes the following issues : OpenSSL Security Advisory 10 September 2019 - CVE-2019-1547: Added ECGROUPsetgenerator side channel attack avoidance. bsc1150003 - CVE-2019-1563: Fixed Bleichenbacher attack against cms/pkcs7 encryption transported key bsc1150250 This update...

Information Disclosure

OpenSSL is vulnerable to information disclosure. It is possible because a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key can be recovered using a Bleichenbacher padding oracle attack after an attacker is notified with status of...

CVE-2019-1563

CVE-2019-1563 describes a Bleichenbacher padding oracle vulnerability in OpenSSL. The issue allows an attacker, after sending a large number of ciphertexts for decryption, to recover the CMS/PKCS7 encryption key or decrypt RSA-encrypted data when the attacker can observe decryption success/failur...

SUSE SLES12 Security Update : compat-openssl098 (SUSE-SU-2015:0553-1)

OpenSSL was updated to fix various security issues. Following security issues were fixed : - CVE-2015-0209: A Use After Free following d2iECPrivatekey error was fixed which could lead to crashes for attacker supplied Elliptic Curve keys. This could be exploited over SSL connections with client...

Medium: openssl

Issue Overview: During key agreement in a TLS handshake using a DHE based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client ha...
