CVE-2021-36048 Exempi vulnerabilities
Title: Exempi vulnerabilities
Summary: Several security issues were fixed in Exempi.
It was discovered that Exempi incorrectly handled certain media files. If a
user or automated system were tricked into opening a specially crafted
file, a remote attacker could cause Exempi to stop responding or crash,
resulting in a denial of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

exempi: NULL pointer dereference in WEBP_Support.hpp:WEBP::GetLE32() allows for denial of service
The WEBP::GetLE32 function in XMPFiles/source/FormatSupport/WEBP_Support.hpp in Exempi 2.4.5 has a NULL pointer dereference.
Exempi is vulnerable to an issue that may manifest as a NULL pointer dereference or an out-of-bounds access due to not checking if vector is of required size before accessing its elements. An attacker could use this to cause a denial of service.
Statement: This issue did not affect the versions of exempi as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for WEBP format in the code of which the vulnerability exists.
