安全等级: 中等
产品: Kylin V3
发布日期: 2019年7月10日
CVE: CVE-2019-13504
CVSS3评分: 6.5
概述:
This issue did not affect the versions of exiv2 as shipped with Kylin Enterprise Linux 7, and 8 as variables MemIo::Impl::size_ and MemIo::Impl::idx_ are of type long, making it impossible to trigger the integer wraparound that would lead to an out-of-bound read. 描述:
There is an out-of-bounds read in Exiv2::MrwImage::readMetadata in mrwimage.cpp in Exiv2 through 0.27.2. A vulnerability was found in exiv2 through versions 0.27.2. An integer wraparound could lead to an out-of-bounds read in the way MemIo is implemented. Reading from the memory buffer with MemIo::Impl::read() reads data beyond the buffer’s limits. An attacker could abuse this flaw by providing a specially crafted image that when read, would cause the application to crash or to leak sensitive data. 系统版本:
KYLIN 3.2.x
KYLIN 3.3.x
KYLIN 3.4.x
