Alpine: libtiffxx, multiple tiff packages: security update to 4.7.2-r0

critical Tenable Self-Hosted Container Security Plugin ID 473840

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow
vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This
flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially
causing a denial of service (application crash) or arbitrary code execution. (CVE-2026-4775)

- A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially
crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the
PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer
overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
(CVE-2026-12912)

- An issue in libtiff 85f2ac8e0b01cb7db2bbecf4a3b891bdbef67938 allows an attacker to execute arbitrary code
via the process_command_opts() function in tools/tiffcrop.c (CVE-2026-52490)

Solution

Update the libtiffxx library and its related packages to version 4.7.2-r0 or later.
