CVE-2015-0242
Description
A buffer overflow flaw was found in the PostgreSQL's internal printf() implementation. An authenticated database user could use a specially crafted string in an SQL query to cause PostgreSQL to crash or, potentially, lead to privilege escalation.
Statement
Not vulnerable. This issue does not affect the version of the postgresql package shipped in Red Hat Enterprise Linux 5, 6, and 7 because it does not use the vulnerable implementation of the snprintf() function provided by postgresql; the glibc implementation of this function, which is not vulnerable to this issue, is used instead.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
