Summary
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
