Beep · Beep · CVE-2018-0492
**Name of the Vulnerable Software and Affected Versions**
beep versions through 1.3.4
**Description**
The issue is related to a race condition in the beep utility's handling of signals, specifically SIGINT and SIGTERM, which can lead to the exploitation of the `free()` function. This exploitation may allow an attacker to gain access to confidential information or block the execution of arbitrary applications by interrupting the `free()` function with another signal, thus disrupting the data structures in use.
**Recommendations**
For versions through 1.3.4, consider removing the setuid bit to prevent local privilege escalation until a patch is available.
As a temporary workaround, consider restricting access to the beep utility to minimize the risk of exploitation.
