This update fixes multiple file format validation vulnerabilities that could result in memory access violations such as buffer overflows and floating point exceptions. It also fixes a regression in hcom parsing introduced when fixing CVE-2017-11358.
CVE-2019-13590
In sox-fmt.h (startread function), there is an integer overflow on the
result of integer addition (wraparound to 0) fed into the lsx_calloc macro
that wraps malloc. When a NULL pointer is returned, it is used without a
prior check that it is a valid pointer, leading to a NULL pointer
dereference on lsx_readbuf in formats_i.c.
CVE-2021-3643
The lsx_adpcm_init function within libsox leads to a
global-buffer-overflow. This flaw allows an attacker to input a malicious
file, leading to the disclosure of sensitive information.
CVE-2021-23159
A vulnerability was found in SoX, where a heap-buffer-overflow occurs
in function lsx_read_w_buf() in formats_i.c file. The vulnerability is
exploitable with a crafted file, that could cause an application to
crash.
CVE-2021-23172
A vulnerability was found in SoX, where a heap-buffer-overflow occurs
in function startread() in hcom.c file. The vulnerability is
exploitable with a crafted hcomn file, that could cause an application
to crash.
CVE-2021-23210
A floating point exception (divide-by-zero) issue was discovered in
SoX in functon read_samples() of voc.c file. An attacker with a
crafted file, could cause an application to crash.
CVE-2021-33844
A floating point exception (divide-by-zero) issue was discovered in
SoX in functon startread() of wav.c file. An attacker with a crafted
wav file, could cause an application to crash.
CVE-2021-40426
A heap-based buffer overflow vulnerability exists in the sphere.c
start_read() functionality of Sound Exchange libsox. A specially-crafted
file can lead to a heap buffer overflow. An attacker can provide a
malicious file to trigger this vulnerability.
CVE-2022-31650
There is a floating-point exception in lsx_aiffstartwrite in aiff.c.
CVE-2022-31651
There is an assertion failure in rate_init in rate.c.
For Debian 8 jessie, these problems have been fixed in version 14.4.1-5+deb8u5.
For Debian 9 stretch, these problems have been fixed in version 14.4.1-5+deb9u3.
We recommend that you upgrade your sox packages.
