K73422160: OpenSSL vulnerability CVE-2019-1547

Security Advisory Description 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 th...

K95463126: OpenSSL vulnerabilities CVE-2016-0703 and CVE-2016-0704

Security Advisory Description CVE-2016-0703 The getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, whic...

K15147: OpenSSL vulnerability CVE-2013-6449

Security Advisory Description The sslgetalgorithm2 function in ssl/s3lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service daemon crash via crafted traffic from a TLS 1.2 client. CVE-2013-6449...

K15150: cURL and libcurl vulnerability CVE-2013-4545

Security Advisory Description cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables the certificate CN and SAN name field verification CURLOPTSSLVERIFYHOST when the digital signature verification CURLOPTSSLVERIFYPEER is disabled, which allows man-in-the-middle attackers to spo...

K27110515: Open SSL vulnerability CVE-2001-1141

Security Advisory Description The Pseudo-Random Number Generator PRNG in SSLeay and OpenSSL before 0.9.6b allows attackers to use the output of small PRNG requests to determine the internal state information, which could be used by attackers to predict future pseudo-random numbers. CVE-2001-1141...

K21665601: OpenSSL vulnerability CVE-2018-0732

Security Advisory Description 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...

K43798238: OpenSSL vulnerability CVE-2019-1551

Security Advisory Description There is an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be ver...

K90492697: OpenSSL vulnerability CVE-2016-6306

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...
