http://security.gentoo.org/

Severity:	normal
Title:	HT Editor: Multiple buffer overflows
Date:	05/10/2005
Bugs:	#91569
ID:	200505-08

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	Architecture(s)
app-editors/hteditor	< 0.8.0-r2	>= 0.8.0-r2	All supported architectures

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"
