CVE-2022-48281 [MEDIUM] LibTIFF vulnerabilities
Title: LibTIFF vulnerabilities
Summary: Several security issues were fixed in LibTIFF.
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.

Title: LibTIFF vulnerabilities
Summary: Several security issues were fixed in LibTIFF.
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

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

libtiff: Buffer Overflow in uv_encode()
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 flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to an out-of-bounds read in the uv_encode function in libtiff/tif_luv.c, resulting in a denial of service.
