Vulnerability from variot - Updated: 2025-01-30 22:09Potential double free in Bluez 5 module of PulseAudio could allow a local attacker to leak memory or crash the program. The modargs variable may be freed twice in the fail condition in src/modules/bluetooth/module-bluez5-device.c and src/modules/bluetooth/module-bluez5-device.c. Fixed in 1:8.0-0ubuntu3.14. PulseAudio There is a double release vulnerability in.Information is obtained and denial of service (DoS) It may be put into a state. ========================================================================== Ubuntu Security Notice USN-4519-1 September 17, 2020
pulseaudio vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
PulseAudio could be made to crash or run programs as your login if it received specially crafted input.
Software Description: - pulseaudio: PulseAudio sound server
Details:
Ratchanan Srirattanamet discovered that an Ubuntu-specific patch caused PulseAudio to incorrectly handle memory under certain error conditions in the Bluez 5 module. An attacker could use this issue to cause PulseAudio to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-15710)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: libpulse-mainloop-glib0 1:8.0-0ubuntu3.14 libpulse0 1:8.0-0ubuntu3.14 pulseaudio 1:8.0-0ubuntu3.14 pulseaudio-module-bluetooth 1:8.0-0ubuntu3.14 pulseaudio-utils 1:8.0-0ubuntu3.14
In general, a standard system update will make all the necessary changes.
