Xiph.org libvorbis 1.2.0 and earlier does not properly handle a zero value for codebook.dim, which allows remote attackers to cause a denial of service (crash or infinite loop) or trigger an integer overflow.

The RedHat Project reports :

Will Drewry of the Google Security Team reported multiple issues in OGG Vorbis and Tremor libraries, that could cause application using those libraries to crash (NULL pointer dereference or divide by zero), enter an infinite loop or cause heap overflow caused by integer overflow.

From Red Hat Security Advisory 2008:0270 :

Updated libvorbis packages that fix various security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

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

The libvorbis packages contain runtime libraries for use in programs that support Ogg Vorbis. Ogg Vorbis is a fully open, non-proprietary, patent-and royalty-free, general-purpose compressed audio format.

Will Drewry of the Google Security Team reported several flaws in the way libvorbis processed audio data. An attacker could create a carefully crafted OGG audio file in such a way that it could cause an application linked with libvorbis to crash, or execute arbitrary code when it was opened. (CVE-2008-1419, CVE-2008-1420, CVE-2008-1423)

Moreover, additional OGG file sanity-checks have been added to prevent possible exploitation of similar issues in the future.

Users of libvorbis are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

Moreover, additional OGG file sanity-checks have been added to prevent possible exploitation of similar issues in the future.

Several security problems were fixed in libvorbis :

  - Division by zero. (CVE-2008-1419)

  - integer overflow. (CVE-2008-1420)

  - integer overflow. (CVE-2008-1423)

It was discovered that libvorbis did not correctly handle certain malformed sound files. If a user were tricked into opening a specially crafted sound file with an application that uses libvorbis, an attacker could execute arbitrary code with the user's privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Will Drewry of the Google Security Team reported several vulnerabilities in how libvorbis processed audio data. An attacker could create a carefully crafted OGG audio file in such a way that it would cause an application linked to libvorbis to crash or possibly execute arbitrary code when opened (CVE-2008-1419, CVE-2008-1420, CVE-2008-1423).

The updated packages have been patched to correct these issues.

The remote host is affected by the vulnerability described in GLSA-200806-09 (libvorbis: Multiple vulnerabilities)

    Will Drewry of the Google Security Team reported multiple     vulnerabilities in libvorbis:
    A zero value for 'codebook.dim' is not properly handled, leading to a     crash, infinite loop or triggering an integer overflow     (CVE-2008-1419).
    An integer overflow in 'residue partition value' evaluation might lead     to a heap-based buffer overflow (CVE-2008-1420).
    An integer overflow in a certain 'quantvals' and 'quantlist'     calculation might lead to a heap-based buffer overflow     (CVE-2008-1423).
  Impact :

    A remote attacker could exploit these vulnerabilities by enticing a     user to open a specially crafted Ogg Vorbis file or network stream with     an application using libvorbis. This might lead to the execution of     arbitrary code with the privileges of the user playing the file or a     Denial of Service by a crash or CPU consumption.
  Workaround :

    There is no known workaround at this time.

Several local (remote) vulnerabilities have been discovered in libvorbis, a library for the Vorbis general-purpose compressed audio codec. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-1419     libvorbis does not properly handle a zero value which     allows remote attackers to cause a denial of service     (crash or infinite loop) or trigger an integer overflow.

  - CVE-2008-1420     Integer overflow in libvorbis allows remote attackers to     execute arbitrary code via a crafted OGG file, which     triggers a heap overflow.

  - CVE-2008-1423     Integer overflow in libvorbis allows remote attackers to     cause a denial of service (crash) or execute arbitrary     code via a crafted OGG file which triggers a heap     overflow.

Several security problems were fixed in libvorbis :

  - CVE-2008-1419 - Division by zero

  - CVE-2008-1420 - integer overflow

  - CVE-2008-1423 - integer overflow
