Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-13108)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in Exiv2 through 0.27.1 due to PngImage::readMetadata mishandles a zero value for iccOffset. A remote attacker can create a crafted PNG image file, trigger integer overflow and perform denial of service (DoS) attack.
2) Integer overflow (CVE-ID: CVE-2019-13109)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in Exiv2 through 0.27.1 due to PngImage::readMetadata mishandles a chunkLength - iccOffset subtraction. A remote attacker can create a crafted PNG image file, trigger integer overflow and perform denial of service (DoS) attack.
3) Integer overflow (CVE-ID: CVE-2019-13110)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to integer overflow in CiffDirectory::readDirectory() function. A remote attacker can create a specially crafted CRW image, pass it to the application, trigger integer overflow and crash the affected application.
4) Integer overflow (CVE-ID: CVE-2019-13111)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to integer overflow in WebPImage::decodeChunks() function. A remote attacker can create a specially crafted WEBP image, pass it to the application, trigger integer overflow and crash the affected application.
5) Resource management error (CVE-ID: CVE-2019-13112)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to memory allocation error in PngChunk::parseChunkContent() function. A remote attacker can create a specially crafted PNG image, pass it to the application and perform a denial of service attack.
6) Reachable Assertion (CVE-ID: CVE-2019-13113)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion due to assertion failure) via an invalid data location in a CRW image file. A remote attacker can cause a denial of service (crash.
7) NULL pointer dereference (CVE-ID: CVE-2019-13114)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error when parsing HTTP responses without a space character. A remote attacker can perform a denial of service (DoS) attack.
8) 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.
