USN-8559-1: rlottie vulnerabilities

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.
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)
