Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2018-5800)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the kodak_ycbcr_load_raw function in internal/dcraw_common.cpp due to an off-by-one error. A local attacker can submit specially crafted images, trigger heap-based buffer overflow and cause the service to crash.
2) NULL pointer dereference (CVE-ID: CVE-2018-5801)
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.The weakness exists in the unpack function src/libraw_cxx.cpp due to incorrect handling of photo files. A remote attacker can submit a specially crafted photo file, trigger NULL pointer dereference and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
3) Out-of-bounds write (CVE-ID: CVE-2018-5802)
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.The weakness exists in the "kodak_radc_load_raw()" function (internal/dcraw_common.cpp) related to the "buf" variable due to incorrect handling of photo files. A remote attacker can submit a specially crafted photo file, trigger out-of-bounds write and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
4) Stack-based buffer overflow (CVE-ID: CVE-2018-5805)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to stack-based buffer overflow within the "quicktake_100_load_raw()" function (internal/dcraw_common.cpp). A local attacker can submit specially crafted images, trigger memory corruption and cause the service to crash.
5) NULL pointer dereference (CVE-ID: CVE-2018-5806)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists due to an error within the "leaf_hdr_load_raw()" function (internal/dcraw_common.cpp). A local attacker can submit specially crafted images, trigger NULL pointer dereference and cause the service to crash.
