CVE-2021-29463 (GCVE-0-2021-29463)

Vulnerability from cvelistv5 – Published: 2021-04-30 00:00 – Updated: 2024-10-15 17:14

Title

Out-of-bounds read in Exiv2::WebPImage::doWriteMetadata

Summary

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `insert`. The bug is fixed in version v0.27.4.

Vulnerability from csaf_certbund - Published: 2021-11-09 23:00 - Updated: 2023-08-23 22:00

Summary

Red Hat Enterprise Linux (exiv2): Mehrere Schwachstellen

Severity

Hoch

Scope

12 vulnerabilities in this advisory, including CVE-2021-29463.

CVE-2021-29463

Es existieren mehrere Schwachstellen in Red Hat Enterprise Linux. Die Fehler bestehen in den Komponenten exiv2 und compat-exiv2-026 aufgrund von mehreren Out-of-bounds-Reads, mehreren Heap-basierten Pufferüberläufen, mehreren Integer-Überläufen, einer Verwendung von nicht initialisiertem Speicher und einer quadratischen Komplexität. Ein Angreifer kann diese Schwachstellen ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen offenzulegen und die Integrität zu gefährden. Eine erfolgreiche Ausnutzung erfordert eine Benutzerinteraktion.

Known affected: 3 products
