USN-8559-1: rlottie vulnerabilities

Publication date

20 July 2026

Overview

rlottie could be made to crash if it received specially crafted input.


Packages

  • rlottie - library for rendering vector based animations and art

Details

It was discovered that rlottie incorrectly handled certain shift
operations. An attacker could possibly use this issue to cause rlottie
to read out of bounds, resulting in a denial of service or exposing
sensitive information. (CVE-2026-10305)

It was discovered that rlottie did not properly limit recursion when
processing certain Lottie animations. An attacker could possibly use
this issue to cause rlottie to crash, resulting in a denial of service.
(CVE-2026-47306)

It was discovered that rlottie incorrectly handled certain span
coordinates. An attacker could possibly use this issue to cause a
stack-based buffer overflow, resulting in a denial of service or
possibly the execution of arbitrary code. (CVE-2026-47318)

It was discovered that rlottie incorrectly handled certain path data.

It was discovered that rlottie incorrectly handled certain path data.
An attacker could possibly use this issue to cause rlottie to allocate
an excessive amount of memory, resulting in a denial of service.
(CVE-2026-47319)

It was discovered that rlottie did not properly limit recursion and
could access an uninitialized pointer when processing certain Lottie
animations. An attacker could possibly use this issue to cause rlottie
to crash, resulting in a denial of service. (CVE-2026-47320)

It was discovered that rlottie incorrectly handled certain array
lengths in the bundled FreeType raster code. An attacker could possibly
use this issue to cause an out-of-bounds write, resulting in a denial
of service or possibly the execution of arbitrary code. This issue only
affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2026-8916)


Update instructions

In general, a standard system update will make all the necessary changes.

Learn more about how to get the fixes.

The problem can be corrected by updating your system to the following package versions:

Ubuntu Release Package Version
26.04 LTS resolute librlottie0-1 –  0.1+dfsg-4.3ubuntu0.1~esm1  
24.04 LTS noble librlottie0-1 –  0.1+dfsg-4ubuntu1.1+esm1  
22.04 LTS jammy librlottie0-1 –  0.1+dfsg-2ubuntu0.2+esm1  
20.04 LTS focal librlottie0-1 –  0~git20200305.a717479+dfsg-1ubuntu0.1~esm3  

Reduce your security exposure

Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
