Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2020-0181)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In exif_data_load_data_thumbnail of exif-data.c, there is a possible denial of service due to an integer overflow. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-145075076
2) Integer overflow (CVE-ID: CVE-2020-0198)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the exif_data_load_data_content() in exif-data.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2020-0452)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a compiler optimization that removes protection against buffer overflow in libexif. A remote attacker can create a specially crafted EXIF file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
