We found several instances of apps that carry sensitive information stating they would share certain information with third-party advertisers and even law enforcement agencies, if necessary.  One of the most popular period-tracking apps on the Google Play store, Period Calendar Period Tracker, has a privacy policy that states it will "share information with law enforcement agencies, public authorities, or other organizations if We’re [sic] required by law to do so or if such use is reasonably necessary.

Ubuntu Security Notice 5647-1 - It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 5615-2 - USN-5615-1 fixed several vulnerabilities in SQLite. This update provides the corresponding fix for CVE-2020-35525 for Ubuntu 16.04 ESM. It was discovered that SQLite incorrectly handled INTERSEC query processing. An attacker could use this issue to cause SQLite to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 5646-1 - Tobias Stoeckmann discovered that libXi did not properly manage memory when handling X server responses. A remote attacker could use this issue to cause libXi to crash, resulting in a denial of service.

The d3-color module provides representations for various color spaces in the browser. Versions prior to 3.1.0 are vulnerable to a Regular expression Denial of Service. This issue has been patched in version 3.1.0. There are no known workarounds.

A buffer overflow in the component nfc_device_load_mifare_ul_data of Flipper Devices Inc., Flipper Zero before v0.65.2 allows attackers to cause a Denial of Service (DoS) via a crafted NFC file.

A vulnerability in /src/amf/amf-context.c in Open5GS 2.4.10 and earlier leads to AMF denial of service.

NULL Pointer Dereference in GitHub repository vim/vim prior to 8.2.4959.

IBM Rational Change 5.3 is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using the SUPP_TEMPLATE_FLAG parameter in a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

There is a use-after-free issue in JBIG2Stream::close() located in JBIG2Stream.cc in Xpdf 4.04. It can be triggered by sending a crafted PDF file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service or possibly have unspecified other impact.
