A vulnerability in the LIEF::MachO::SegmentCommand::virtual_address function of LIEF v0.12.1 allows attackers to cause a denial of service (DOS) through a segmentation fault via a crafted MachO file.

An issue was discovered in Bento4 1.6.0-639. A memory leak exists in AP4_StdcFileByteStream::Create(AP4_FileByteStream*, char const*, AP4_FileByteStream::Mode, AP4_ByteStream*&) in System/StdC/Ap4StdCFileByteStream.cpp.

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.

Ubuntu Security Notice 5645-1 - Jacob Champion discovered that PostgreSQL incorrectly handled SSL certificate verification and encryption. A remote attacker could possibly use this issue to inject arbitrary SQL queries when a connection is first established. Tom Lane discovered that PostgreSQL incorrect handled certain array subscripting calculations. An authenticated attacker could possibly use this issue to overwrite server memory and escalate privileges.

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.

An issue was discovered in the Linux kernel through version 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges. The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access. The issue exists in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.

Ubuntu Security Notice 5644-1 - 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. Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service.

ETAP Lighting International NV ETAP Safety Manager 1.0.0.32 is vulnerable to Cross Site Scripting (XSS). Input passed to the GET parameter 'action' is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML/JS code in a user's browser session in context of an affected site.
