Gentoo: 202310-11 Urgent: OpenSSL ASN.1 Parsing Denial of Service

GENTOO LINUX SECURITY ANNOUNCEMENT 200309-19
     GENTOO BUG # : 30001


DESCRIPTION

quote from OpenSSL advisory:

"1. Certain ASN.1 encodings that are rejected as invalid by the parser
can trigger a bug in the deallocation of the corresponding data
structure, corrupting the stack. This can be used as a denial of service
attack. It is currently unknown whether this can be exploited to run
malicious code. This issue does not affect OpenSSL 0.9.6.

2. Unusual ASN.1 tag values can cause an out of bounds read under
certain circumstances, resulting in a denial of service vulnerability.

3. A malformed public key in a certificate will crash the verify code if
it is set to ignore public key decoding errors. Public key decode errorsare not normally ignored, except for debugging purposes, so this is
unlikely to affect production code. Exploitation of an affected
application would result in a denial of service vulnerability.

4. Due to an error in the SSL/TLS protocol handling, a server will pars...
