A null pointer dereference issue was found in Libtiff's tif_dir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial of service. (CVE-2023-2908)

A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones. (CVE-2023-3316)

A vulnerability was found in SourceCodester Resort Management System 1.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality. The manipulation of the argument page leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. (CVE-2023-3618)

libtiff 4.5.0 is vulnerable to Buffer Overflow in /libtiff/tools/tiffcrop.c:8499. Incorrect updating of buffer size after rotateImage() in tiffcrop cause heap-buffer-overflow and SEGV. (CVE-2023-25433)

loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted TIFF image. (CVE-2023-26965)

libtiff 4.5.0 is vulnerable to Buffer Overflow in uv_encode() when libtiff reads a corrupted little-endian TIFF file and specifies the output to be big-endian. (CVE-2023-26966)

It was discovered that LibTIFF was not properly handling variables used to perform memory management operations when processing an image through tiffcrop, which could lead to a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2023-25433, CVE-2023-26965)

It was discovered that LibTIFF was not properly processing numerical values when dealing with little-endian input data, which could lead to the execution of an invalid operation. An attacker could possibly use this issue to cause a denial of service (CVE-2023-26966)

It was discovered that LibTIFF was not properly performing bounds checks when closing a previously opened TIFF file, which could lead to a NULL pointer dereference. An attacker could possibly use this issue to cause a denial of service. (CVE-2023-3316)

It was discovered that LibTIFF could be made to write out of bounds when processing certain malformed image files with the tiffcrop utility. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-48281)

It was discovered that LibTIFF incorrectly handled certain image files. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 23.04. (CVE-2023-2731)

It was discovered that LibTIFF incorrectly handled certain image files with the tiffcp utility. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcp to crash, resulting in a denial of service. (CVE-2023-2908)

It was discovered that LibTIFF incorrectly handled certain file paths. If a user were tricked into specifying certain output paths, an attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2023-3316)

It was discovered that LibTIFF did not properly managed memory when processing certain malformed image files with the tiffcrop utility. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-26965)

It was discovered that LibTIFF contained an arithmetic overflow. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause a denial of service. (CVE-2023-38288, CVE-2023-38289)
