Hope it is OK to assign this to you, DavidG. You did several 'recent' updates to it.

Comment 2 Nicolas Salguero 2021-11-16 12:09:09 CET
Suggested advisory:

The updated package fixes security vulnerabilities:

Buffer overflow vulnerability in function stbi__extend_receive in stb_image.h in stb 2.26 via a crafted JPEG file. (CVE-2021-28021)

An issue was discovered in stb stb_image.h 1.33 through 2.27. The HDR loader parsed truncated end-of-file RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused denial of service in applications using stb_image by submitting crafted HDR files. (CVE-2021-42715)

An issue was discovered in stb stb_image.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location. (CVE-2021-42716)

Comment 3 Herman Viaene 2021-11-20 11:06:26 CET
MGA8-64 Plasma on Lenovo B50
No installation issues.
The info in MCC reads: "curaengine - Engine for processing 3D models into G-code instructions for 3D printers​"
Sincce this is no previous update, and no wiki, and this 3D is untrodden territory for me, all I can say it apparently does not disturb anything else.
Leaving for others who might have more knowledge and experience on the subject.
