Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-13504)
The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability exists due to an out-of-bounds read error in the "Exiv2::MrwImage::readMetadata" function in the "mrwimage.cpp" file. A remote attacker can create a specially crafted media file, trick the victim into opening it and cause the affected application to crash.
2) Out-of-bounds read (CVE-ID: CVE-2019-14370)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within Exiv2::MrwImage::readMetadata() in mrwimage.cpp. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and perform a denial of service attack.
3) Out-of-bounds read (CVE-ID: CVE-2019-14369)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when processing a crafted image file within the Exiv2::PngImage::readMetadata() in pngimage.cpp. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and crash the affected application.
4) Out-of-bounds read (CVE-ID: CVE-2019-14368)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a heap-based buffer over-read in Exiv2::RafImage::readMetadata() in rafimage.cpp. A remote attacker can perform a denial of service attack.
