Heap-based buffer overflow in the strip_escapes function in signal.c in GNU ed before 1.0 allows context-dependent or user-assisted attackers to execute arbitrary code via a long filename. NOTE: since ed itself does not typically run with special privileges, this issue only crosses privilege boundaries when ed is invoked as a third-party component.

The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party components and libraries :

  - bind
  - expat
  - glib2
  - Kernel
  - newt
  - nfs-utils
  - NTP
  - OpenSSH
  - OpenSSL

From Red Hat Security Advisory 2008:0946 :

An updated ed package that fixes one security issue is now available for Red Hat Enterprise Linux 2.1, 3, 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

ed is a line-oriented text editor, used to create, display, and modify text files (both interactively and via shell scripts).

A heap-based buffer overflow was discovered in the way ed, the GNU line editor, processed long file names. An attacker could create a file with a specially crafted name that could possibly execute an arbitrary code when opened in the ed editor. (CVE-2008-3916)

Users of ed should upgrade to this updated package, which contains a backported patch to resolve this issue.

(CWE-119)

a. vMA and Service Console update for newt to 0.52.2-12.el5_4.1

   Newt is a programming library for color text mode, widget based    user interfaces. Newt can be used to add stacked windows, entry    widgets, checkboxes, radio buttons, labels, plain text fields,    scrollbars, etc., to text mode user interfaces.

   A heap-based buffer overflow flaw was found in the way newt    processes content that is to be displayed in a text dialog box.
   A local attacker could issue a specially crafted text dialog box    display request (direct or via a custom application), leading to a    denial of service (application crash) or, potentially, arbitrary    code execution with the privileges of the user running the    application using the newt library.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2905 to this issue.

b. vMA and Service Console update for vMA package nfs-utils to    1.0.9-42.el5

   The nfs-utils package provides a daemon for the kernel NFS server    and related tools.

   It was discovered that nfs-utils did not use tcp_wrappers    correctly.  Certain hosts access rules defined in '/etc/hosts.allow'    and '/etc/hosts.deny' may not have been honored, possibly allowing    remote attackers to bypass intended access restrictions.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2008-4552 to this issue.

c. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1

   GLib is the low-level core library that forms the basis for    projects such as GTK+ and GNOME. It provides data structure    handling for C, portability wrappers, and interfaces for such    runtime functionality as an event loop, threads, dynamic loading,    and an object system.

   Multiple integer overflows in glib/gbase64.c in GLib before 2.20    allow context-dependent attackers to execute arbitrary code via a    long string that is converted either from or to a base64    representation.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2008-4316 to this issue.

d. vMA and Service Console update for openssl to 0.9.8e-12.el5

   SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-    strength cryptography world-wide.

   Multiple denial of service flaws were discovered in OpenSSL's DTLS    implementation. A remote attacker could use these flaws to cause a    DTLS server to use excessive amounts of memory, or crash on an    invalid memory access or NULL pointer dereference.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-1377, CVE-2009-1378,    CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues.

   An input validation flaw was found in the handling of the BMPString    and UniversalString ASN1 string types in OpenSSL's    ASN1_STRING_print_ex() function. An attacker could use this flaw to    create a specially crafted X.509 certificate that could cause    applications using the affected function to crash when printing    certificate contents.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-0590 to this issue.

e. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1

   It was discovered that BIND was incorrectly caching responses    without performing proper DNSSEC validation, when those responses    were received during the resolution of a recursive client query    that requested DNSSEC records but indicated that checking should be    disabled. A remote attacker could use this flaw to bypass the DNSSEC    validation check and perform a cache poisoning attack if the target    BIND server was receiving such client queries.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4022 to this issue.

f. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2.

   Two buffer over-read flaws were found in the way Expat handled    malformed UTF-8 sequences when processing XML files. A specially-    crafted XML file could cause applications using Expat to fail while    parsing the file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-3560 and CVE-2009-3720 to these    issues.

g. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2

   A Red Hat specific patch used in the openssh packages as shipped in    Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain    ownership requirements for directories used as arguments for the    ChrootDirectory configuration options. A malicious user that also    has or previously had non-chroot shell access to a system could    possibly use this flaw to escalate their privileges and run    commands as any system user.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2904 to this issue.

h. vMA and Service Console package ntp updated to    ntp-4.2.2p1-9.el5_4.1.i386.rpm

   A flaw was discovered in the way ntpd handled certain malformed NTP    packets. ntpd logged information about all such packets and replied    with an NTP packet that was treated as malformed when received by    another ntpd. A remote attacker could use this flaw to create an NTP    packet reply loop between two ntpd servers through a malformed packet    with a spoofed source IP address and port, causing ntpd on those    servers to use excessive amounts of CPU time and fill disk space with    log messages.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3563 to this issue.   

i. vMA update for package kernel to 2.6.18-164.9.1.el5

   Updated vMA package kernel addresses the security issues listed    below.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2009-2849 to the security issue fixed in    kernel 2.6.18-128.2.1
