A buffer overflow vulnerability in WhatsApp VOIP stack allowed remote code execution via specially crafted series of RTCP packets sent to a target phone number. The issue affects WhatsApp for Android prior to v2.19.134, WhatsApp Business for Android prior to v2.19.44, WhatsApp for iOS prior to v2.19.51, WhatsApp Business for iOS prior to v2.19.51, WhatsApp for Windows Phone prior to v2.18.348, and WhatsApp for Tizen prior to v2.18.15.

vcodec2_hls_filter in libvoipCodec_v7a.so in the WeChat application through 7.0.3 for Android allows attackers to cause a denial of service (application crash) by replacing an emoji file (under the /sdcard/tencent/MicroMsg directory) with a crafted .wxgf file. The content of the replacement must be derived from the phone's IMEI. The crash occurs upon receiving a message that contains the replaced emoji.

The Simple - Better Banking application 2.45.0 through 2.45.3 (fixed in 2.46.0) for Android was affected by an information disclosure vulnerability that leaked the user's password to the keyboard autocomplete functionality. Third-party Android keyboards that capture the password may store this password in cleartext, or transmit the password to third-party services for keyboard customization purposes. A compromise of any datastore that contains keyboard autocompletion caches would result in the disclosure of the user's Simple Bank password.

A bug in WhatsApp for Android's messaging logic would potentially allow a malicious individual who has taken over over a WhatsApp user's account to recover previously sent messages. This behavior requires independent knowledge of metadata for previous messages, which are not available publicly. This issue affects WhatsApp for Android 2.19.52 and 2.19.54 - 2.19.103, as well as WhatsApp Business for Android starting in v2.19.22 until v2.19.38.

The Rediffmail (aka com.rediff.mail.and) application 2.2.6 for Android has cleartext mail content in file storage, persisting after a logout.

An issue was discovered in the Ascensia Contour NEXT ONE application for Android before 2019-01-15. It has a statically coded initialization vector. Extraction of the initialization vector is necessary for deciphering communications between this application and the backend server. This, in combination with retrieving any user's encrypted data from the Ascensia cloud through another vulnerability, allows an attacker to obtain and modify any patient's medical information.
