Synopsis
=======
Two vulnerabilities have been discovered in HT Editor, potentially leading to the execution of arbitrary code.
Background
=========
HT is a hex editor, designed to help analyse and modify executable files.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-editors/hteditor lt; 0.8.0-r2 gt;= 0.8.0-r2
Description
==========
Tavis Ormandy of the Gentoo Linux Security Team discovered an integer overflow in the ELF parser, leading to a heap-based buffer overflow. The vendor has reported that an unrelated buffer overflow has been discovered in the PE parser.
Impact
=====
Successful exploitation would require the victim to open a specially crafted file using HT, potentially permitting an attacker to execute arbitrary code.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All hteditor users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=app-editors/hteditor-0.8.0-r2"
Availability
===========
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200505-08.xml
Concerns?
========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
