CWE-476  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:7 php-pgsql.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-pgsql package and not the php-pgsql package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The php_pgsql_meta_data function in pgsql.c in the PostgreSQL (aka pgsql) extension in PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not validate token extraction for table names, which might allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted name. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1352.
