I disclosured a crash in potplayer last year : https://seclists.org/fulldisclosure/2021/Mar/76
And I found a new one this year, this time is a mid file. Again I contacted
Korea Internet & Security Agency(first-team () krcert or kr), they shared
report to the onwer of the potplayer, Kakao Corp as they said. But I did
not get any update after about half a year. So this is a 0day.
I cannot debug or get any useful information about the crash…
USN-5745-1 fixed vulnerabilities in shadow. Unfortunately that update
introduced a regression that caused useradd to behave incorrectly in Ubuntu
14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. This
update reverts the security fix pending further investigation.
We apologize for the inconvenience.
Original advisory details:
Florian Weimer discovered that shadow was not properly copying and removing
user directory trees, which could lead to a race condition. A local attacker
could possibly use this issue to setup a symlink attack and alter or remove
directories without authorization.
The package com.github.samtools:htsjdk before 3.0.1 are vulnerable to Creation of Temporary File in Directory with Insecure Permissions due to the createTempDir() function in util/IOUtil.java not checking for the existence of the temporary directory before attempting to create it.
It was discovered that Sysstat incorrectly handled certain arithmetic
multiplications. An attacker could use this issue to cause Sysstat to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
It was discovered that Bind incorrectly handled large query name when using
lightweight resolver protocol. A remote attacker could use this issue to
consume resources, leading to a denial of service. (CVE-2016-2775)
It was discovered that Bind incorrectly handled large zone data size
received via AXFR response. A remote authenticated attacker could use this
issue to consume resources, leading to a denial of service. This issue only
affected Ubuntu 16.04 LTS. (CVE-2016-6170)
The user_id and device_id on the Ourphoto App version 1.4.1 /device/* end-points both suffer from insecure direct object reference vulnerabilities. Other end-users user_id and device_id values can be enumerated by incrementing or decrementing id numbers. The impact of this vulnerability allows an attacker to discover sensitive information such as end-user email addresses, and their unique frame_token value of all other Ourphoto App end-users.
The /device/signin end-point for the Ourphoto App version 1.4.1 discloses clear-text password information for functionality within the picture frame devices. The deviceVideoCallPassword and mqttPassword are returned in clear-text. The lack of sessions management and presence of insecure direct object references allows to return password information for other end-users devices. Many of the picture frame devices offer video calling, and it is likely this information can be used to abuse that functionality.
