Vulnerability in OpenSSL - ASN.1 structure reuse memory corruption

ASN.1 structure reuse memory corruption. Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. Such reuse is and has been strongly discouraged and is believed to be rare. Found by Emilia Käsper OpenSSL development team...

openssl: multiple issues

CVE-2015-1787 denial of service If client auth is used then a server can segfault in the event of a DHE ciphersuite being selected and a zero length ClientKeyExchange message being sent by the client. This could be exploited in a DoS attack. - CVE-2015-0207 denial of service The DTLSv1listen...

Vulnerability in OpenSSL - Segmentation fault in ASN1_TYPE_cmp

Segmentation fault in ASN1TYPEcmp. The function ASN1TYPEcmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1TYPEcmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verification operation and...

Vulnerability in OpenSSL - PKCS7 NULL pointer dereferences

PKCS7 NULL pointer dereference. The PKCS7 parsing code does not handle missing outer ContentInfo correctly. An attacker can craft malformed ASN.1-encoded PKCS7 blobs with missing content and trigger a NULL pointer dereference on parsing. Applications that verify PKCS7 signatures, decrypt PKCS7 da...

CVE-2015-0208

The ASN.1 signature-verification implementation in the rsaitemverify function in crypto/rsa/rsaameth.c in OpenSSL 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service NULL pointer dereference and application crash via crafted RSA PSS parameters to an endpoint that uses the...

CVE-2015-0289

The PKCS7 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 does not properly handle a lack of outer ContentInfo, which allows attackers to cause a denial of service NULL pointer dereference and application crash by leveraging an applicati...

PolarSSL 'asn1_get_sequence_of' Function Uninitialized Pointer RCE

PolarSSL contains a flaw when parsing ASN.1 sequences from X.509 certificates due to freeing an uninitialized pointer by the function 'asn1getsequenceof' within file 'asn1parse.c'. An unauthenticated, remote attacker, using a specially crafted certificate, can exploit this flaw to cause a denial ...

CVE-2015-1182

The asn1getsequenceof function in library/asn1parse.c in PolarSSL 1.0 through 1.2.12 and 1.3.x through 1.3.9 does not properly initialize a pointer in the asn1sequence linked list, which allows remote attackers to cause a denial of service crash or possibly execute arbitrary code via a crafted...

polarssl: remote code execution

During the parsing of a ASN.1 sequence, a pointer in the linked list of asn1sequence is not initialized by asn1getsequenceof. In case an error occurs during parsing of the list, a situation is created where the uninitialized pointer is passed to polarsslfree. This sequence can be triggered when a...
