Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-9232)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a missing bounds check when processing media content in libvpx. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
2) Input validation error (CVE-ID: CVE-2019-9433)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied input when processing media content in libvpx. A remote attacker can pass specially crafted file to the application and gain access to sensitive information.
3) Out-of-bounds read (CVE-ID: CVE-2019-9325)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a missing bounds check when processing media content in libvpx. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
