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 < 0.8.0-r2 >= 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 ">=app-editors/hteditor-0.8.0-r2"
