1) Out-of-bounds read

EUVDB-ID: #VU14018

Risk: Low

CVSSv4.0: 4.7 [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]

CVE-ID: CVE-2018-13300

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

Exploit availability: No

Description

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

Mitigation

Update the affected packages.

EUVDB-ID: #VU14532

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-15822

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

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

The vulnerability exists due to insufficient checks for an empty audio packet by the flv_write_packet function, as defined in the libavformat/flvenc.c source code file. A local attacker can access the system and execute a specially crafted application that submits malicious input to trigger an assertion failure and cause the service to crash.

Mitigation

Update the affected packages.
