Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Heap-based buffer over-read (CVE-ID: CVE-2018-10999)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the Exiv2::Internal::PngChunk::parseTXTChunk function. A remote attacker can perform a denial of service attack.
2) Memory corruption (CVE-ID: CVE-2018-10958)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to boundary error in types.cpp when processing a large size value. A remote attacker can perform Exiv2::Internal::PngChunk::zlibUncompress call and cause a SIGABRT during an attempt at memory allocation.
3) Denial of service (CVE-ID: CVE-2018-10998)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error in readMetadata in jp2image.cpp. A remote attacker can trigger an incorrect Safe::add call and cause a denial of service (SIGABRT)
4) Heap-based buffer overflow (CVE-ID: CVE-2018-11531)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer overflow in getData in preview.cpp. A remote attacker can trigger memory corruption and perform a denial of service attack.
5) Memory corruption (CVE-ID: CVE-2018-12264)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflows in LoaderTiff::getData() in preview.cpp. A remote attacker can trigger out-of-bounds read in Exiv2::ValueType::setDataArea in value.hpp and perform a denial of service attack.
6) Memory corruption (CVE-ID: CVE-2018-12265)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in the LoaderExifJpeg class in preview.cpp. A remote attacker can trigger out-of-bounds read in Exiv2::MemIo::read in basicio.cpp and perform a denial of service attack.
7) Heap-based buffer overflow (CVE-ID: CVE-2018-14046)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash.
