Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
The crypt_gensalt functions for BSDI-style extended DES-based and FreeBSD-sytle MD5-based password hashes in crypt_blowfish 0.4.7 and earlier do not evenly and randomly distribute salts, which makes it easier for attackers to guess passwords from a stolen password file due to the increased number of collisions.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

This update has been rated as having important security impact by the Red Hat Security Response Team. PostgreSQL is an advanced Object-Relational database management system (DBMS). A bug was found in the way PostgreSQL's PQescapeString function escapes strings when operating in a multibyte character encoding. It is possible for an attacker to provide an application a carefully crafted string containing invalidly-encoded characters, which may be improperly escaped, allowing the attacker to inject malicious SQL. While this update fixes how PQescapeString operates, the PostgreSQL server has also been modified to prevent such an attack occurring through unpatched clients. (CVE-2006-2313, CVE-2006-2314). More details about this issue are available in the linked PostgreSQL technical documentation. An integer signedness bug was found in the way PostgreSQL generated password salts. The actual salt size is only half the size of the expected salt, making the process of brute forcing password hashes slightly easier. This update will not strengthen already existing passwords, but all newly assigned passwords will have the proper salt length. (CVE-2006-0591) Users of PostgreSQL should upgrade to these updated packages containing PostgreSQL version 7.4.13, which corrects these issues." ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012906.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?25da7d4d" ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012907.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?3bce9c62" ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012910.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?a2810143" ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012911.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?bd654928" ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012925.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?3c19efa7" ); # https://lists.centos.org/pipermail/centos-announce/2006-May/012926.html script_set_attribute( attribute:"see_also", value:"http://www.nessus.org/u?45b7bf81" ); script_set_attribute( attribute:"solution", value:"Update the affected postgresql packages." ); script_set_cvss_base_vector("CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P"); script_set_cvss_temporal_vector("CVSS2#E:U/RL:OF/RC:C"); script_set_attribute(attribute:"exploitability_ease", value:"No known exploits are available"); script_set_attribute(attribute:"exploit_available", value:"false"); script_set_attribute(attribute:"plugin_type", value:"local"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-contrib"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-devel"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-docs"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-jdbc"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-libs"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-pl"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-python"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-server"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-tcl"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:postgresql-test"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-contrib"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-devel"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-docs"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-jdbc"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-libs"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-pl"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-python"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-server"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-tcl"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:centos:centos:rh-postgresql-test"); script_set_attribute(attribute:"cpe", value:"cpe:/o:centos:centos:3"); script_set_attribute(attribute:"cpe", value:"cpe:/o:centos:centos:4"); script_set_attribute(attribute:"vuln_publication_date", value:"2006/02/07"); script_set_attribute(attribute:"patch_publication_date", value:"2006/05/24"); script_set_attribute(attribute:"plugin_publication_date", value:"2006/07/03"); script_set_attribute(attribute:"generated_plugin", value:"current"); script_end_attributes(); script_category(ACT_GATHER_INFO); script_copyright(english:"This script is Copyright (C) 2006-2019 and is owned by Tenable, Inc. or an Affiliate thereof."); script_family(english:"CentOS Local Security Checks"); script_dependencies("ssh_get_info.nasl"); script_require_keys("Host/local_checks_enabled", "Host/CentOS/release", "Host/CentOS/rpm-list"); exit(0); } include("audit.inc"); include("global_settings.inc"); include("rpm.inc"); if (!get_kb_item("Host/local_checks_enabled")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED); release = get_kb_item("Host/CentOS/release"); if (isnull(release) || "CentOS" >!< release) audit(AUDIT_OS_NOT, "CentOS"); os_ver = pregmatch(pattern: "CentOS(?: Linux)?
