Amazon Linux AMI Security Advisory: ALAS-2015-468
Advisory Release Date: 2015-01-08 12:38 Pacific
Advisory Updated Date: 2015-01-08 12:40 Pacific
Severity:
Medium
Issue Overview:
An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application. (CVE-2014-6040)
It was found that the wordexp() function would perform command substitution even when the WRDE_NOCMD flag was specified. An attacker able to provide specially crafted input to an application using the wordexp() function, and not sanitizing the input correctly, could potentially use this flaw to execute arbitrary commands with the credentials of the user running that application. (CVE-2014-7817)
