CVE-2023-1916: A flaw was found in tiffcrop, a program distributed by the libtiff package.
Noroxi assessment
Priority: Monitor (action score 24/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
- Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: CBL Mariner 1.0 ARM 4.5.1-1; CBL Mariner 1.0 x64 4.5.1-1; CBL Mariner 2.0 ARM 4.5.1-1.
Low priority for now. Upgrade to CBL Mariner 1.0 ARM 4.5.1-1; CBL Mariner 1.0 x64 4.5.1-1; CBL Mariner 2.0 ARM 4.5.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
A flaw was found in tiffcrop, a program distributed by the libtiff package. A specially crafted tiff file can lead to an out-of-bounds read in the extractImageSection function in tools/tiffcrop.c, resulting in a denial of service and limited information disclosure. This issue affects libtiff versions 4.x.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
