Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-3700)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in WIN WLAN Host. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
2) Use-after-free (CVE-ID: CVE-2019-10580)
The vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in HLOS. A local attacker can gain elevated privileges on the target system.
3) Use-after-free (CVE-ID: CVE-2020-3701)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in Camera Driver. A remote attacker can gain elevated privileges on the target system.
4) Out-of-bounds read (CVE-ID: CVE-2020-3688)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in Video while parsing mp4 clip with corrupted sample atoms. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
5) Use-after-free (CVE-ID: CVE-2020-3671)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in Multimedia when generating a frame buffer in OpenGL ES. A remote attacker can gain elevated privileges on the target system.
6) Out-of-bounds write (CVE-ID: CVE-2020-3698)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in WLAN Host. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
7) Buffer overflow (CVE-ID: CVE-2020-3699)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WLAN HOST. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
