1) NULL pointer dereference (CVE-ID: CVE-2023-49460)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the UncompressedImageCodec::decode_uncompressed_image() function. A remote attacker can trick the victim to open a specially crafted media file and perform a denial of service (DoS) attack.


2) Use-after-free (CVE-ID: CVE-2023-49464)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the UncompressedImageCodec::get_luma_bits_per_pixel_from_configuration_unci() function. A remote attacker can trick the victim to open a specially crafted media file, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


3) Buffer overflow (CVE-ID: CVE-2023-49462)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in /libheif/exif.cc. A remote attacker can create a specially crafted media 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.


4) Buffer overflow (CVE-ID: CVE-2023-49463)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the find_exif_tag() function in /libheif/exif.cc. A remote attacker can create a specially crafted media file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
