OpenSSL ASN.1 parser insecure memory deallocation

Overview A vulnerability in the way OpenSSL deallocates memory used to store ASN.1 structures could allow a remote attacker to execute arbitrary code with the privileges of the process using the OpenSSL library. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer...

CVE-2003-0430

CVE-2003-0430 concerns Ethereal (Wireshark) 0.9.12 and earlier, where the SPNEGO dissector is vulnerable to processing an invalid ASN.1 value. This can allow remote attackers to cause a denial of service (crash). The affected component is the SPNEGO dissector within Ethereal’s protocol analyzer. ...

CVE-2003-0430

The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service crash via an invalid ASN.1 value...

CVE-2002-0036

Integer signedness error in MIT Kerberos V5 ASN.1 decoder before krb5 1.2.5 allows remote attackers to cause a denial of service via a large unsigned data element length, which is later used as a negative value...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS. Integer signedness error in MIT Kerberos V5 ASN.1 decoder before krb5 1.2.5 allows remote attackers to cause a denial of service via a large unsigned data element length, which is later used as a negative value...

MIT Kerberos V5 ASN.1 decoder fails to perform bounds checking on data element length fields

Overview The MIT Kerberos V5 implementation contains an ASN.1 decoding flaw that may allow remote attackers to crash affected Kerberos applications. Description Kerberos V5 protocol messages are defined using Abstract Syntax Notation One ASN.1, a formal language that allows protocol specification...

ASN.1 parsing errors exist in implementations of SSL, TLS, S/MIME, PKCS#7 routines

Overview Abstract Syntax Notation number One ASN.1 is an international standard used to describe and transmit data packets between applications and across networks. There is a vulnerability related to ASN.1 that could permit an attacker to cause a denial of service or potentially execute arbitrar...

[SECURITY] [DSA-130-1] memory allocation error in ethereal

Package: ethereal Vulnerability: remotely triggered memory allocation error Debian-specific: no Ethereal versions prior to 0.9.3 were vulnerable to an allocation error in the ASN.1 parser. This can be triggered when analyzing traffic using the SNMP, LDAP, COPS, or Kerberos protocols in ethereal...

CVE-2002-0353

The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to cause a denial of service crash via a certain malformed packet, which causes Ethereal to allocate memory incorrectly, possibly due to zero-length fields...

CVE-2002-0353

Concrete details found: CVE-2002-0353 affects Ethereal 0.9.2 and earlier, stemming from the ASN.1 parser, enabling remote denial of service via a malformed packet that triggers improper memory allocation (possibly due to zero-length fields). Public advisories reference multiple vendors (Debian, R...
