Packages

  • tiff - Tag Image File Format (TIFF) library

Details

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...
