Sox · Sox · CVE-2019-13590
**Name of the Vulnerable Software and Affected Versions**
SoX version 14.4.2
**Description**
An issue in the `startread` function of `sox-fmt.h` in the `libsox.a` library of SoX leads to an integer overflow, resulting in a NULL pointer being returned from the `lsx calloc` macro, which wraps `malloc`. This NULL pointer is then used without validation, causing a NULL pointer dereference in `lsx readbuf` in `formats i.c`. The vulnerability can be exploited by a remote attacker to cause a denial of service.
**Recommendations**
For SoX version 14.4.2, as a temporary workaround, consider restricting the use of the `startread` function in `sox-fmt.h` until a patch is available.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
