Patches should fix all CVEs reported by `guix lint`: CVE-2015-7747; CVE-2017-6827, CVE-2017-6828, CVE-2017-6829, CVE-2017-6830, CVE-2017-6831, CVE-2017-6832, CVE-2017-6833, CVE-2017-6834, CVE-2017-6835, CVE-2017-6836, CVE-2017-6837, CVE-2017-6838, CVE-2017-6839; CVE-2018-13440; CVE-2018-17095 Since the patches do not reference to CVEs, it's a bit hard to tell which patch actually closes which CVE. Debian reports all these to be closed by the patches below and NixPkgs provides references. * gnu/packages/audio.scm (audiofile): New variable. * gnu/packages/patches/audiofile-fix-datatypes-in-tests.patch, gnu/packages/patches/audiofile-fix-sign-conversion.patch, gnu/packages/patches/audiofile-CVE-2015-7747.patch, gnu/packages/patches/audiofile-CVE-2018-13440.patch, gnu/packages/patches/audiofile-CVE-2018-17095.patch, gnu/packages/patches/audiofile-Check-the-number-of-coefficients.patch, gnu/packages/patches/audiofile-Fail-on-error-in-parseFormat.patch, gnu/packages/patches/audiofile-Fix-index-overflow-in-IMA.cpp.patch, gnu/packages/patches/audiofile-Fix-multiply-overflow-sfconvert.patch, gnu/packages/patches/audiofile-Fix-overflow-in-MSADPCM-decodeSam.patch, gnu/packages/patches/audiofile-division-by-zero-BlockCodec-runPull.patch, gnu/packages/patches/audiofile-hurd.patch, gnu/packages/patches/audiofile-signature-of-multiplyCheckOverflow.patch: New files. * gnu/local.mk: Add them.

Subject: Actually fail when error occurs in parseFormat
|
|
|
|
When there's an unsupported number of bits per sample or an invalid
|
|
number of samples per block, don't only print an error message using
|
|
the error handler, but actually stop parsing the file.
|
|
|
|
This fixes #35 (also reported at
|
|
https://bugzilla.opensuse.org/show_bug.cgi?id=1026983 and
