Summary
Red Hat Security Advisory: : Updated PostgreSQL packages fix buffer overrun vulnerabilities
Severity
Important
Notes
Topic: Updated PostgreSQL packages are available for Red Hat Linux 6.2, 7, 7.1, and 7.2 where we have backported a number of security fixes. A separate advisory deals with updated PostgreSQL packages for Red Hat Linux 7.3 and 8.0.
Details: PostgreSQL is an advanced Object-Relational database management system (DBMS). A number of security issues have been found that affect PostgreSQL versions shipped with Red Hat Linux. Buffer overflows in PostgreSQL 7.2 allow attackers to cause a denial of service and possibly execute arbitrary code via long arguments to the lpad or rpad functions. CAN-2002-0972 Buffer overflow in the cash_words() function for PostgreSQL 7.2 and earlier allows local users to cause a denial of service and possibly execute arbitrary code via a malformed argument. CAN-2002-1397 Buffer overflow in the date parser for PostgreSQL before 7.2.2 allows attackers to cause a denial of service and possibly execute arbitrary code via a long date string, also known as a vulnerability "in handling long datetime input." CAN-2002-1398 Heap-based buffer overflow in the repeat() function for PostgreSQL before 7.2.2 allows attackers to execute arbitrary code by causing repeat() to generate a large string. CAN-2002-1400 Buffer overflows in circle_poly, path_encode and path_add allow attackers to cause a denial of service and possibly execute arbitrary code. Note that these issues have been fixed in our packages and in PostgreSQL CVS, but are not included in PostgreSQL version 7.2.2 or 7.2.3. CAN-2002-1401 Buffer overflows in the TZ and SET TIME ZONE enivronment variables for PostgreSQL 7.2.1 and earlier allow local users to cause a denial of service and possibly execute arbitrary code. CAN-2002-1402 Note that these vulnerabilities are only critical on open or shared systems because connecting to the database is required before the vulnerabilities can be exploited. The PostgreSQL Global Development Team has released versions of PostgreSQL that fixes these vulnerabilities, and these fixes have been isolated and backported to the various versions of PostgreSQL that originally shipped with each Red Hat Linux distribution. All users of PostgreSQL are advised to install these updated packages.

Threats
Impact Important
CVE-2002-1397

Vulnerability in the cash_words() function for PostgreSQL 7.2 and earlier allows local users to cause a denial of service and possibly execute arbitrary code via a large negative argument, possibly triggering an integer signedness error or buffer overflow.

Affected products
Fixed 4 products, the same list as for CVE-2002-0972
Threats
Impact Important
CVE-2002-1398

Buffer overflow in the date parser for PostgreSQL before 7.2.2 allows attackers to cause a denial of service and possibly execute arbitrary code via a long date string, aka a vulnerability "in handling long datetime input."

Affected products
Fixed 4 products, the same list as for CVE-2002-0972
Threats
Impact Important
CVE-2002-1400

Heap-based buffer overflow in the repeat() function for PostgreSQL before 7.2.2 allows attackers to execute arbitrary code by causing repeat() to generate a large string.

Affected products
Fixed 4 products, the same list as for CVE-2002-0972
Threats
Impact Important
CVE-2002-1401

Buffer overflows in (1) circle_poly, (2) path_encode and (3) path_add (also incorrectly identified as path_addr) for PostgreSQL 7.2.3 and earlier allow attackers to cause a denial of service and possibly execute arbitrary code, possibly as a result of an integer overflow.

Affected products
Fixed 4 products, the same list as for CVE-2002-0972
Threats
Impact Moderate
CVE-2002-1402

Buffer overflows in the (1) TZ and (2) SET TIME ZONE enivronment variables for PostgreSQL 7.2.1 and earlier allow local users to cause a denial of service and possibly execute arbitrary code.

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
