Description

CVE-2006-2362

Jesus Olmos Gonzalez discovered a buffer overflow in the Tektronix Hex Format (TekHex) backend of the BFD library, such as used by the 'strings' utility. By tricking an user or automated system into processing a specially crafted file with 'strings' or a vulnerable third-party application using the BFD library, this could be exploited to crash the application, or possibly even execute arbitrary code with the privileges of the user.

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