Severity: Normal
Title: libsndfile: User-assisted execution of arbitrary code
Date: May 27, 2009
Bugs: #269863
ID: 200905-09


Synopsis

Multiple heap-based buffer overflow vulnerabilities in libsndfile might
allow remote attackers to execute arbitrary code.

Background

libsndfile is a C library for reading and writing files containing
sampled sound.

Affected packages

-------------------------------------------------------------------
 Package                /  Vulnerable  /                Unaffected
-------------------------------------------------------------------

1 media-libs/libsndfile < 1.0.20 >= 1.0.20

Description

The following vulnerabilities have been found in libsndfile:

  • Tobias Klein reported that the header_read() function in
    src/common.c uses user input for calculating a buffer size, possibly
    leading to a heap-based buffer overflow (CVE-2009-1788).

  • The vendor reported a boundary error in the aiff_read_header()
    function in src/aiff.c, possibly leading to a heap-based buffer
    overflow (CVE-2009-1791).

Impact

A remote attacker could entice a user to open a specially crafted AIFF
or VOC file in a program using libsndfile, possibly resulting in the
execution of arbitrary code with the privileges of the user running the
application.

Workaround

There is no known workaround at this time.

Resolution

All libsndfile users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libsndfile-1.0.20&quot;
