SB2017081740 - Input validation error in Glibc

Description

This security bulletin contains information about 1 vulnerability.

1) Input validation error (CVE-ID: CVE-2009-4880)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple integer overflows in the strfmon implementation in the GNU C Library (aka glibc or libc6) 2.10.1 and earlier allow context-dependent attackers to cause a denial of service (memory consumption or application crash) via a crafted format string, as demonstrated by a crafted first argument to the money_format function in PHP, a related issue to CVE-2008-1391.

Remediation

Install update from vendor's website.
