Package : exim
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0021
Debian Bug : 289046

Philip Hazel announced a buffer overflow in the host_aton
function in exim, the default mail-tranport-agent in Debian, which
can lead to the execution of arbitrary code via an illegal IPv6
address.

For the stable distribution (woody) this problem has been fixed
in version 3.35-1woody4.

For the unstable distribution (sid) this problem has been fixed
in version 3.36-13 of exim and 4.34-10 of exim4.

We recommend that you upgrade your exim and exim4 packages.

Package : glibc
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2004-0968
BugTraq ID : 11286
Debian Bug : 279680 278278 205600

Several insecure uses of temporary files have been discovered in
support scripts in the libc6 package which provices the c library
for a GNU/Linux system. Trustix developers found that the catchsegv
script uses temporary files insecurely. Openwall developers
discovered insecure temporary files in the glibcbug script. These
scripts are vulnerable to a symlink attack.

For the stable distribution (woody) these problems have been
fixed in version 2.2.5-11.8.

For the unstable distribution (sid) these problems have been
fixed in version 2.3.2.ds1-20.

We recommend that you upgrade your libc6 package.

Gentoo Linux Security Advisory GLSA 200501-13


http://security.gentoo.org/


Severity: Normal
Title: pdftohtml: Vulnerabilities in included Xpdf
Date: January 10, 2005
Bugs: #75200
ID: 200501-13


Synopsis

pdftohtml includes vulnerable Xpdf code to handle PDF files,
making it vulnerable to execution of arbitrary code upon converting
a malicious PDF file.

Background

pdftohtml is a utility to convert PDF files to HTML or XML
formats. It makes use of Xpdf code to decode PDF files.

Affected packages


     Package             /  Vulnerable  /                   Unaffected

  1  app-text/pdftohtml      < 0.36-r2                      >= 0.36-r2

Description

Xpdf is vulnerable to integer overflows, as described in GLSA
200412-24.

Impact

An attacker could entice a user to convert a specially-crafted
PDF file, potentially resulting in the execution of arbitrary code
with the rights of the user running pdftohtml.

Workaround

There is no known workaround at this time.

Resolution

All pdftohtml users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/pdftohtml-0.36-r2"

Severity: High
Title: poppassd_pam: Unauthorized password changing
Date: January 11, 2005
Bugs: #75820
ID: 200501-22


Synopsis

poppassd_pam allows anyone to change any user’s password without
authenticating the user first.

Background

poppassd_pam is a PAM-enabled server for changing system
passwords that can be used to change POP server passwords.

Affected packages


     Package                 /  Vulnerable  /               Unaffected


net-mail/poppassd_ceti <= 1.0 >= 1.8.4 net-mail/poppassd_pam <= 1.0 Vulnerable!

Description

Gentoo Linux developer Marcus Hanwell discovered that
poppassd_pam did not check that the old password was valid before
changing passwords. Our investigation revealed that poppassd_pam
did not call pam_authenticate before calling pam_chauthtok.

Impact

A remote attacker could change the system password of any user,
including root. This leads to a complete compromise of the POP
accounts, and may also lead to a complete root compromise of the
affected server, if it also provides shell access authenticated
using system passwords.

Workaround

There is no known workaround at this time.

Resolution

All poppassd_pam users should migrate to the new package called
poppassd_ceti:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-mail/poppassd_ceti-1.8.4"

Note: Portage will automatically replace the poppassd_pam
package by the poppassd_ceti package.

Severity: Normal
Title: o3read: Buffer overflow during file conversion
Date: January 11, 2005
Bugs: #74478
ID: 200501-20


Synopsis

A buffer overflow in o3read allows an attacker to execute
arbitrary code by way of a specially crafted XML file.

Background

o3read is a standalone converter for OpenOffice.org files. It
allows a user to dump the contents tree (o3read) and convert to
plain text (o3totxt) or to HTML (o3tohtml) Writer and Calc
files.

Affected packages


     Package          /  Vulnerable  /                      Unaffected

  1  app-text/o3read      <= 0.0.3                            >= 0.0.4

Description

Wiktor Kopec discovered that the parse_html function in o3read.c
copies any number of bytes into a 1024-byte t[] array.

Impact

Using a specially crafted file, possibly delivered by e-mail or
over the Web, an attacker may execute arbitrary code with the
permissions of the user running o3read.

Workaround

There is no known workaround at this time.

Resolution

All o3read users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/o3read-0.0.4"

Severity: Normal
Title: HylaFAX: hfaxd unauthorized login vulnerability
Date: January 11, 2005
Bugs: #75941
ID: 200501-21


Synopsis

HylaFAX is subject to a vulnerability in its username matching
code, potentially allowing remote users to bypass access control
lists.

Background

HylaFAX is a software package for sending and receiving
facsimile messages.

Affected packages


     Package           /  Vulnerable  /                     Unaffected

  1  net-misc/hylafax     < 4.2.0-r2                       >= 4.2.0-r2

Description

The code used by hfaxd to match a given username and hostname
with an entry in the hosts.hfaxd file is insufficiently protected
against malicious entries.

Impact

If the HylaFAX installation uses a weak hosts.hfaxd file, a
remote attacker could authenticate using a malicious username or
hostname and bypass the intended access restrictions.

Workaround

As a workaround, administrators may consider adding passwords to
all entries in the hosts.hfaxd file.

Resolution

All HylaFAX users should upgrade to the latest version:

    # emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/hylafax-4.2.0-r2"

Note: Due to heightened security, weak entries in the
hosts.hfaxd file may no longer work. Please see the HylaFAX
documentation for details of accepted syntax in the hosts.hfaxd
file.

Mandrakelinux Security Update Advisory


Package name: nfs-utils
Advisory ID: MDKSA-2005:005
Date: January 11th, 2005
Affected versions: 10.0, 10.1, 9.2, Corporate Server 2.1


Problem Description:

Arjan van de Ven discovered a buffer overflow in rquotad on
64bit architectures; an improper integer conversion could lead to a
buffer overflow. An attacker with access to an NFS share could send
a specially crafted request which could then lead to the execution
of arbitrary code.

The updated packages are provided to prevent this issue.
