Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-14973)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attacks.
The vulnerability exists due to integer overflow in the "_TIFFCheckMalloc" and "_TIFFCheckRealloc" functions in the "tif_aux.c" file. A remote attacker can trick a victim to open a specially crafted file that contains crafted TIFF images, trigger integer overflow and crash the target application.
2) Integer overflow (CVE-ID: CVE-2019-17546)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when processing RGBA images. A remote attacker can create a specially crafted RGBA image, pass it to the affected 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) Integer overflow (CVE-ID: CVE-2020-35523)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the the tif_getimage.c file in libtiff. A remote attacker can pass specially crafted file to the application, trigger an integer overflow 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-2020-35524)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing TIFF images in libtiff's TIFF2PDF tool. A remote attacker can create a specially crafted TIFF image, 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.
5) Integer overflow (CVE-ID: CVE-2022-3970)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the TIFFReadRGBATileExt() function in libtiff/tif_getimage.c. A remote attacker can trick the victim to open a specially crafted TIFF file, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Heap-based buffer overflow (CVE-ID: CVE-2022-48281)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the processCropSelections() function in tools/tiffcrop.c in LibTIFF. A remote attacker can pass a specially crafted TIFF image 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.
