CVE-2022-24614 : Exploit Details and Defense Strategies
CVE-2022-24614 allows attackers to trigger out-of-memory errors by manipulating JPEG files in metadata-extractor, leading to denial of service. Learn the impact and mitigation steps.
When reading a specially crafted JPEG file, metadata-extractor up to 2.16.0 can be made to allocate large amounts of memory that finally leads to an out-of-memory error even for very small inputs. This could be used to mount a denial of service attack against services that use metadata-extractor library.
Understanding CVE-2022-24614
This CVE involves a vulnerability in metadata-extractor that could allow attackers to cause denial of service attacks.
What is CVE-2022-24614?
CVE-2022-24614 is a vulnerability in metadata-extractor library versions up to 2.16.0 that could be exploited by reading a specially crafted JPEG file to allocate excessive memory, leading to out-of-memory errors.
The Impact of CVE-2022-24614
The impact of this vulnerability is the potential for attackers to exhaust system memory resources, causing denial of service against services utilizing the metadata-extractor library.
