A PngChunk::parseChunkContent uncontrolled memory allocation in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (crash due to an std::badalloc exception) via a crafted PNG image file.

Exiv2 through 0.27.1 allows an attacker to cause a denial of service (crash due to assertion failure) via an invalid data location in a CRW image file.

A vulnerability was discovered in http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a denial of service (crash due to a NULL pointer dereference) by returning a crafted response that lacks a space character.

An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted PNG image file, because PngImage::readMetadata mishandles a chunkLength - iccOffset subtraction.

An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted PNG image file, because PngImage::readMetadata mishandles a zero value for iccOffset.

A WebPImage::decodeChunks integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (large heap allocation followed by a very long running loop) via a crafted WEBP image file.

A buffer overflow vulnerability in the Databuf function in types.cpp of Exiv2 v0.27.1 leads to a denial of service (DOS).
