Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A buffer overflow vulnerability in libsndfile might allow remote
attackers to execute arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
libsndfile is a C library for reading and writing files containing
sampled sound.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libsndfile < 1.0.19 >=3D 1.0.19
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Alin Rad Pop from Secunia Research reported an integer overflow when
processing CAF description chunks, leading to a heap-based buffer
overflow.
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could entice a user to open a specially crafted CAF
file, resulting in the remote execution of arbitrary code with the
privileges of the user running the application.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All libsndfile users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dmedia-libs/libsndfile-1.0.19"=
