openssl: CA certificate check bypass with X509_V_FLAG_X509_STRICT
A flaw was found in openssl. The flag that enables additional security checks of certificates present in a certificate chain was not enabled allowing a confirmation step to verify that certificates in the chain are valid CA certificates is bypassed. The highest threat from this vulnerability is t...

Important: openssl11
Issue Overview: A flaw was found in openssl. A server crash and denial of service attack could occur if a client sends a TLSv1.2 renegotiation ClientHello and omits the signaturealgorithms extension but includes a signaturealgorithmscert extension. The highest threat from this vulnerability is to...
DEBIAN-CVE-2021-23839
OpenSSL 1.0.2 supports SSLv2. If a client attempts to negotiate SSLv2 with a server that is configured to support both SSLv2 and more recent SSL and TLS versions then a check is made for a version rollback attack when unpadding an RSA signature. Clients that support SSL or TLS versions greater th...
OpenSSL: Double-free in DSA code
A double-free flaw was found in the way OpenSSL parsed certain malformed DSA Digital Signature Algorithm private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash...
openssl: Out-of-bounds write caused by unchecked errors in BN_bn2dec()
An out of bounds write flaw was discovered in the OpenSSL BNbn2dec function. An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code...
openssl: certificate message OOB reads
Multiple out of bounds read flaws were found in the way OpenSSL handled certain TLS/SSL protocol handshake messages. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL...
Heartbleed Persists on 200,000 Servers, Devices
Almost 200,000 servers and devices are still vulnerable to Heartbleed, the OpenSSL flaw patched nearly three years ago. The numbers come from search engine Shodan, which released data showing U.S. servers hosted on Amazon AWS are disproportionately vulnerable to the flaw. “There’s a lot to be...
DEBIAN-CVE-2016-2181
The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service false-positive packet drops via spoofed DTLS records, related to reclayerd1...
The vulnerability of the OpenSSL software allows a malicious attacker to compromise the accessibility of protected information.
A memory leak in the tlsdecryptticket function in t1lib.c of OpenSSL allows malicious actors operating remotely to trigger a service failure excessive memory consumption by using a specially crafted session credential, which causes a verification error for integrity checking...
OpenSSL: SSLv2 doesn't block disabled ciphers
A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks...

openssl: Divide-and-conquer session key recovery in SSLv2
It was discovered that the SSLv2 servers using OpenSSL accepted SSLv2 connection handshakes that indicated non-zero clear key length for non-export cipher suites. An attacker could use this flaw to decrypt recorded SSLv2 sessions with the server by using it as a decryption oracle...
openssl: TLS protocol downgrade attack
A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions...

HP System Management Homepage < 7.4 Multiple Vulnerabilities
According to the web server's banner, the version of HP System Management Homepage SMH hosted on the remote web server is affected by the following vulnerabilities : - A flaw exists within the included cURL that disables the 'CURLOPTSSLVERIFYHOST' check when the setting on 'CURLOPTSSLVERIFYPEER' ...
DEBIAN-CVE-2014-0198
The dossl3write function in s3pkt.c in OpenSSL 1.x through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, does not properly manage a buffer pointer during certain recursive calls, which allows remote attackers to cause a denial of service NULL pointer dereference and application crash via vectors...
openssl: DTLS plaintext recovery attack
The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack...
