Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-3570)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in tiffcrop.c utility in libtiff when processing TIFF files. A remote attacker can pass specially crafted file to the application, 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) Out-of-bounds write (CVE-ID: CVE-2022-3597)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF images within the _TIFFmemcpy() function in libtiff/tif_unix.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
3) Out-of-bounds read (CVE-ID: CVE-2022-3599)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the writeSingleSection() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
4) Out-of-bounds write (CVE-ID: CVE-2022-3598)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF images within the extractContigSamplesShifted24bits() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF image to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
5) Out-of-bounds write (CVE-ID: CVE-2022-3626)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF images within the _TIFFmemset() function in libtiff/tif_unix.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
6) Out-of-bounds write (CVE-ID: CVE-2022-3627)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF images within the _TIFFmemcpy() function in libtiff/tif_unix.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
