Gentoo Linux Security Advisory

Title: libsndfile: User-assisted execution of arbitrary code (GLSA 200905-09)
Severity: normal
Exploitable: remote
Date: May 27, 2009
Bug(s): #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: media-libs/libsndfile
Vulnerable: < 1.0.20
Unaffected: >= 1.0.20
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.20"
