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 ">=media-libs/libsndfile-1.0.20" References ========== [ 1 ] CVE-2009-1788 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1788 [ 2 ] CVE-2009-1791 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1791 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200905-09.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
