Augeas is vulnerable to heap-based buffer overflow due to improper handling of escaped strings. Attacker could send crafted strings that would cause the application using augeas to copy past the end of a buffer, leading to a crash or possible code execution.

For Debian 7 ‘Wheezy’, these problems have been fixed in version 0.10.0-1+deb7u1.

We recommend that you upgrade your augeas packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
