Description

This security bulletin contains information about 7 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2018-6392)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition.

The vulnerability exists in the filter_slice function in libavfilter/vf_transpose.c due to insufficient input validation. A remote attacker can trick the victim into opening a specially crafted MP4 file that submits malicious input, trigger a out-of-bounds read and cause the service to crash.


2) Out-of-bounds read (CVE-ID: CVE-2018-6621)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition.

The vulnerability exists in the decode_frame function in libavcodec/utvideodec.c due to insufficient input validation. A remote attacker can trick the victim into opening a specially crafted AVI file that submits malicious input, trigger a out-of-bounds read and cause the service to crash.


3) Out-of-bounds read (CVE-ID: CVE-2018-7557)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the decode_init function due to out-of-bounds read. A remote attacker can trick the victim into opening a specially crafted Audio Video Interleave (AVI) file with the affected application, trigger memory corruption and cause the service to crash.

4) Out-of-bounds read (CVE-ID: CVE-2018-10001)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote unauthenticated attacker to cause DoS condition.

The vulnerability exists in the decode_init function in libavcodec/utvideodec.c due to insufficient input validation. A remote attacker can trick the victim into opening a specially crafted AVI file that submits malicious input, trigger a out-of-bounds read and cause the service to crash.


5) Assertion violation (CVE-ID: CVE-2018-12458)

CWE-ID: CWE-617 - Reachable Assertion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to improper integer type in the mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c. A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger assertion violation and cause the service to crash.


6) Out-of-bounds read (CVE-ID: CVE-2018-13300)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to improper argument (AVCodecParameters) passed to the avpriv_request_sample function in the handle_eac3 function in libavformat/movenc.c. A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger out-of-bounds read and cause the service to crash or possibly access arbitrary data


7) Out-of-bounds read (CVE-ID: CVE-2018-13302)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to improper handling of frame types of multiple independent substreams in the handle_eac3 function in libavformat/movenc.c in EAC3_FRAME_TYPE_INDEPENDENT). A remote attacker can supply specially crafted AVI file to MPEG4, trick the victim into converting it, trigger out-of-bounds read and cause the service to crash.
