Security Advisory Description The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before 1.0.2i might allow remote attackers to cause a denial of service out-of-bounds read via crafted certificate operations, related to s3clnt.c and s3srvr.c. CVE-2016-6306 Impact This vulnerability may allo...

K09422508: OpenSSL vulnerabilities CVE-2016-6307 and CVE-2016-6308

Security Advisory Description CVE-2016-6307 The state-machine implementation in OpenSSL 1.1.0 before 1.1.0a allocates memory before checking for an excessive length, which might allow remote attackers to cause a denial of service memory consumption via crafted TLS messages, related to...

K52171694: OpenSSL vulnerability CVE-2021-3450

Security Advisory Description The X509VFLAGX509STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curv...

K00053434: OPENSSL_LH_flush() function vulnerability CVE-2022-1473

Security Advisory Description The OPENSSLLHflush function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or...

K15328: OpenSSL vulnerability CVE-2010-5298

Security Advisory Description Race condition in the ssl3readbytes function in s3pkt.c in OpenSSL through 1.0.1g, when SSLMODERELEASEBUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service use-after-free and parsing error via an SSL connection in a...

K19559038: OpenSSL vulnerability CVE-2021-3712

Security Advisory Description ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which i...

K83823933: OpenSSL Vulnerability CVE-2021-4044

Security Advisory Description Internally libssl in OpenSSL calls X509verifycert on the client side to verify a certificate supplied by a server. That function may return a negative return value to indicate an internal error for example out of memory. Such a negative return value is mishandled by...

K43452233: OpenSSL vulnerability CVE-2017-3737

Security Advisory Description OpenSSL 1.0.2 starting from version 1.0.2b introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This...

K15564: TLS vulnerability CVE-2014-3511

Security Advisory Description The ssl23getclienthello function in s23srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS...

K16938: OpenSSL vulnerability CVE-2015-1788

Security Advisory Description The BNGF2mmodinv function in crypto/bn/bngf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allows...

K16937: OpenSSL vulnerability CVE-2015-1793

Security Advisory Description Description The X509verifycert function in crypto/x509/x509vfy.c in OpenSSL 1.0.1n, 1.0.1o, 1.0.2b, and 1.0.2c does not properly process X.509 Basic Constraints CA values during identification of alternative certificate chains, which allows remote attackers to spoof ...

K13597: OpenSSL vulnerability CVE-2012-1165

Security Advisory Description The mimeparamcmp function in crypto/asn1/asnmime.c in OpenSSL before 0.9.8u and 1.x before 1.0.0h allows remote attackers to cause a denial of service NULL pointer dereference and application crash using a crafted S/MIME message; a different vulnerability than...

K43570545: OpenSSL vulnerability CVE-2016-7055

Security Advisory Description There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private...

K16135: OpenSSL vulnerability CVE-2015-0205

Security Advisory Description The ssl3getcertverify function in s3srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman DH certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without...

K15295: OpenSSL vulnerability CVE-2014-0076

Security Advisory Description The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack. CVE-2014-0076 Impact...
