NISCC Vulnerability Advisory IPSEC - 004033
Abstract: Three attacks that apply to certain configurations of IPsec have been identified. These configurations use Encapsulating Security Payload ESP in tunnel mode with confidentiality only, or with integrity protection being provided by a higher layer protocol. Some configurations using AH to...
IPsec configurations may be vulnerable to information disclosure
Overview The IPsec Encapsulating Security Payload protocol used in tunneling mode may be vulnerable to multiple attacks when confidentiality mode is used without integrity protection, or in certain cases where integrity protection is provided by higher-level protocols. Description The IP Security...
Postgres: pg_hba.conf, md5, pg_shadow, encrypted passwords
Greetings, There appears to be some deficiencies in both the documentation of the 'md5' authentication methology in pghba.conf and in the md5 hash generation which is stored in pgshadow. The md5 hash which is generated for and stored in pgshadow does not use a random salt but instead uses the...
