Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-1354)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the TIFFReadRawDataStriped() function in tiffinfo.c. A remote attacker can pass specially crafted TIFF file to the application that is using the affected library, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2022-1355)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within tiffcp.c when processing TIFF files. A remote attacker can pass specially crafted TIFF file to the application that is using the affected library, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Out-of-bounds read (CVE-ID: CVE-2022-1622)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary condition in LZWDecode() function in libtiff/tif_lzw.c:619. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it, trigger out-of-bounds read error and to perform a denial of service attack.
4) Out-of-bounds read (CVE-ID: CVE-2022-1623)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary condition in LZWDecode() function in libtiff/tif_lzw.c:624. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it, trigger out-of-bounds read error and perform a denial of service attack.
