Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2018-6616)
The vulnerability allows a local unauthenticated attacker to cause DoS condition on the target system.The weakness exists in the opj_t1_encode_cblks function, which is defined in the openjp2/t1.c source code file, due to insufficient validation of user-supplied input. A local attacker can submit a specially crafted BMP file and cause the service to crash.
2) Divide-by-zero (CVE-ID: CVE-2018-14423)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to multiple division-by-zero conditions that exist in the pi_next_pcrl, pi_next_cprl, and pi_next_rpcl functions, as defined in the lib/openjp3d/pi.c source code file. A remote attacker can trick the victim into opening a specially crafted file with an application that uses the affected library and cause the affected application to crash.
3) Out-of-bounds write (CVE-ID: CVE-2018-16376)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An issue was discovered in OpenJPEG 2.3.0. A heap-based buffer overflow was discovered in the function t2_encode_packet in lib/openmj2/t2.c. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly unspecified other impact.
4) Buffer overflow (CVE-ID: CVE-2018-16375)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An issue was discovered in OpenJPEG 2.3.0. Missing checks for header_info.height and header_info.width in the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow.
5) NULL pointer dereference (CVE-ID: CVE-2018-18088)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dreference error in the imagetopnm function of jp2/convert. A remote attacker can perform a denial of service (DoS) attack.
