Vulnerability Title
Denial of service due to FPE in Exiv2::Internal::resolveLens0xffff
Vulnerability Description
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A floating point exception (FPE) due to an integer divide by zero was found in Exiv2 versions v0.27.4 and earlier. The FPE is triggered when Exiv2 is used to print 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 printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.

Vulnerability Title
Exiv2 数字错误漏洞
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 0.27.4之前版本存在数字错误漏洞，该漏洞源于软件中发现了一个浮点异常，该异常是由整数除零引起的。当使用Exiv2打印图像文件的元数据时，会触发浮点异常。攻击者可利用该漏洞诱骗受害者在一个特制的图像文件上运行Exiv2，那么攻击者可能会利用该漏洞导致拒绝服务。
