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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
