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:
