Gentoo Linux Security Advisory

Title: Newt: User-assisted execution of arbitrary code (GLSA 201006-14)
Severity: normal
Exploitable: remote
Date: June 02, 2010
Bug(s): #285854
ID: 201006-14

Synopsis


A heap-based buffer overflow in the Newt library might allow remote,
user-assisted attackers to execute arbitrary code.


Background


Newt is a library for displaying text mode user interfaces.


Affected Packages

Package: dev-libs/newt
Vulnerable: < 0.52.10-r1
Unaffected: >= 0.52.10-r1
Architectures: All supported architectures


Description


Miroslav Lichvar reported that Newt is prone to a heap-based buffer
overflow in textbox.c.


Impact


A remote attacker could entice a user to enter a specially crafted
string into a text dialog box rendered by Newt, possibly resulting in
the remote execution of arbitrary code with the privileges of the user
running the application, or a Denial of Service condition.


Workaround


There is no known workaround at this time.


Resolution


All Newt users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/newt-0.52.10-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 26, 2009. It is likely that your system is
already no longer affected by this issue.
