Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2017-9110)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in hufDecode function in ImfHuf.cpp. A remote attacker can perform denial of service (DoS) attack.
2) Out-of-bounds write (CVE-ID: CVE-2017-9111)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in storeSSE function in ImfOptimizedPixelReading.h. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
3) Out-of-bounds read (CVE-ID: CVE-2017-9112)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in getBits function in ImfHuf.cpp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
4) Out-of-bounds write (CVE-ID: CVE-2017-9113)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in bufferedReadPixels function in ImfInputFile.cpp. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
5) Out-of-bounds read (CVE-ID: CVE-2017-9114)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the refill function in ImfFastHuf.cpp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
6) Out-of-bounds write (CVE-ID: CVE-2017-9115)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the = operator function in half.h. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
7) Out-of-bounds read (CVE-ID: CVE-2017-9116)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the uncompress function in ImfZip.cpp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
