CVE-2023-26966

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.

This libtiff provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. The latest version of the TIFF specification is available on-line in several different formats.And contains command-line programs for manipulating TIFF format image files using the libtiff library.

Security Fix(es):

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

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)

A null pointer dereference issue was discovered in Libtiff's tif_dir.c file. This flaw allows an attacker to pass a crafted TIFF image file to the tiffcp utility, which triggers runtime error, causing an undefined behavior, resulting in an application crash, eventually leading to a denial of service.(CVE-2023-2908)

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.

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.

Security Fix(es):

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.

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)
