Vulnerability Title
Denial of service due to assertion failure in crwimage_int.cpp
Vulnerability Description
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The assertion failure is triggered when Exiv2 is used to modify the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when modifying 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 `fi`. ### Patches The bug is fixed in version v0.27.5. ### References Regression test and bug fix: #1739 ### For more information Please see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security.

Vulnerability Title
Exiv2 安全漏洞
Vulnerability Description
Exiv2是Andreas Huggel个人开发者的一套用于管理图像元数据的C++库和命令行应用程序。该产品提供了读取和写入EXIF、IPTC和XMP等多种格式图像元数据的功能。 Exiv2存在安全漏洞，该漏洞用于读取、写入、删除和修改映像文件的元数据。当使用Exiv2修改精心制作的映像文件的元数据时，会触发断言失败。如果攻击者可利用该漏洞可以诱骗受害者在一个精心制作的图像文件上运行Exiv2，那么攻击者可利用该漏洞可能会利用该漏洞导致拒绝服务。
