Frugalware Security Announcements (FSAs)

This is a list of security announcments that have been released for the current stable version of Frugalware

libwpd

  • Author: voroskoi
  • Vulnerable: 0.8.8-1
  • Unaffected: 0.8.9-1terminus1

Some vulnerabilities have been reported in libwpd, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise an application using the library.

  1. An integer overflow within the “WP6GeneralTextPacket::_readContents” function can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into opening a specially crafted WordPerfect document in an application using the library.
  2. Boundary errors within the “WP3TablesGroup::_readContents()” and “WP5DefinitionGroup_DefineTablesSubGroup::WP5DefinitionGroup_DefineTablesSubGroup()” functions can be exploited to cause heap-based buffer overflows by e.g. tricking a user into opening a specially crafted WordPerfect document in an application using the library. Successful exploitation may allow the execution of arbitrary code.

CVEs:

mplayer

  • Author: voroskoi
  • Vulnerable: mplayer-1.0rc1-3
  • Unaffected: mplayer-1.0rc1-4terminus1

Some vulnerabilities have been reported in MPlayer, which can potentially be exploited by malicious people to compromise a user’s system. The vulnerabilities are caused due to boundary errors in the “DMO_VideoDecoder_Open()” function in loader/dmo/DMO_VideoDecoder.c and in the “DS_VideoDecoder_Open()” function in loader/dshow/DS_VideoDecoder.c. These can be exploited to cause heap-based buffer overflows and may allow execution of arbitrary code via a specially crafted media file.

CVEs:

gnupg

  • Author: voroskoi
  • Vulnerable: 1.4.5-3siwenna1
  • Unaffected: 1.4.5-4siwenna1

Gerardo Richarte from Core Security Technologies identified a problem when using GnuPG in streaming mode. The problem is actually a variant of a well known problem in the way signed material is presented in a MUA. It is possible to insert additional text before or after a signed (or signed and encrypted) OpenPGP message and make the user believe that this additional text is also covered by the signature.

tcpdump

  • Author: voroskoi
  • Vulnerable: 3.9.4-1
  • Unaffected: 3.9.4-2siwenna1

Moritz Jodeit has reported a vulnerability in tcpdump, which potentially can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an off-by-one error within the “parse_elements()” function in print-802.11.c. This can be exploited to cause a one byte buffer overflow via a specially crafted 802.11 frame.

CVEs:

blender

  • Author: voroskoi
  • Vulnerable: 2.42a-2
  • Unaffected: 2.42a-3siwenna1

Secunia Research has discovered a vulnerability in Blender, which can be exploited by malicious people to compromise a user’s system. The vulnerability is caused due to the insecure use of the “eval()” function in kmz_ImportWithMesh.py. This can be exploited to execute arbitrary Python commands by tricking a user into importing a specially crafted “*.kml” or “*.kmz” file.

CVEs:

dropbear

  • Author: voroskoi
  • Vulnerable: 0.48.1-2
  • Unaffected: 0.49-1siwenna1

A weakness has been reported in Dropbear, which can be exploited by malicious people to bypass certain security restrictions. The weakness is caused due to Dropbear not warning users sufficiently if a hostkey changed, which makes it easier for attackers to e.g. conduct man-in-the-middle attacks.

CVEs:

thunderbird

  • Author: voroskoi
  • Vulnerable: 1.5.0.9-1siwenna1
  • Unaffected: 1.5.0.10-1siwenna1

Some vulnerabilities have been reported in Mozilla Thunderbird, which potentially can be exploited by malicious people to compromise a user’s system.

  1. An integer overflow within the handling of emails formatted as text/richtext or text/enhanced may be exploited to execute arbitrary code, but requires that a malicious email includes a 400 megabyte long line.
  2. An integer underflow error in the Network Security Services (NSS) code when processing SSLv2 server messages can be exploited to cause a heap-based buffer overflow via a certificate with a public key too small to encrypt the “Master Secret”. Successful exploitation may allow execution of arbitrary code.
  3. Multiple memory corruption errors exist in the layout engine, JavaScript engine, and in SVG. Some of these may be exploited to execute arbitrary code on a user’s system.

CVEs:

seamonkey

  • Author: voroskoi
  • Vulnerable: 1.0.7-1siwenna1
  • Unaffected: 1.0.8-1siwenna1

Multiple vulnerabilities have been reported in Mozilla SeaMonkey, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting and spoofing attacks, gain knowledge of sensitive information, and potentially compromise a user’s system.

  1. An error in the handling of the “locations.hostname” DOM property can be exploited to bypass certain security restrictions.
  2. An integer underflow error in the Network Security Services (NSS) code when processing SSLv2 server messages can be exploited to cause a heap-based buffer overflow via a certificate with a public key too small to encrypt the “Master Secret”. Successful exploitation may allow execution of arbitrary code.
  3. It is possible to conduct cross-site scripting attacks against sites containing a frame with a “data:” URI as source. Successful exploitation requires that a user is tricked into visiting a malicious website and opening a blocked popup.
  4. It is possible to open windows containing local files thereby stealing the contents when the full path of a locally saved file containing malicious script code is known. This can be exploited in combination with a flaw in the seeding of the pseudo-random number generator causing downloaded files to be saved to temporary files with a somewhat predictable name. Successful exploitation requires that a user is tricked into visiting a malicious website and opening a blocked popup.
  5. Browser UI elements like the host name and security indicators can be spoofed using a specially crafted custom cursor and manipulating the CSS3 hotspot property.
  6. It may be possible to gain knowledge of sensitive information from a website due to an error resulting in two web pages colliding in the disk cache thereby potentially appending part of one document to the other. Successful exploitation requires that a user is tricked into visiting a malicious website while visiting the target website.
  7. Various errors in the Mozilla parser when handling invalid trailing characters in HTML tag attribute names and during processing of UTF-7 content when child frames inherit the character set of its parent window can be exploited to conduct cross-site scripting attacks.
  8. A vulnerability in the Password Manager may be exploited to conduct phishing attacks.
  9. Multiple memory corruption errors exist in the layout engine, JavaScript engine, and in SVG. Some of these may be exploited to execute arbitrary code on a user’s system.
  10. An error within the handling of the onUnload event handler and self-modifying document.write() calls can be exploited to corrupt memory and potentially execute arbitrary code.
