A new Linux security vulnerability dubbed Looney Tunables has been discovered in the GNU C library's ld.so dynamic loader that, if successfully exploited, could lead to a local privilege escalation and allow a threat actor to gain root privileges. Tracked as CVE-2023-4911 (CVSS score: 7.8), the issue is a buffer overflow that resides in the dynamic loader's processing of the GLIBC_TUNABLES

By Waqas Dubbed Looney Tunables; the vulnerability has existed since its introduction in April 2021, putting a significant number of systems at risk. This is a post from HackRead.com Read the original post: Linux Vulnerability Exposes Millions of Systems to Attack

A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.

Buffer Overflow vulnerability in Vorbis-tools v.1.4.2 allows a local attacker to execute arbitrary code and cause a denial of service during the conversion of wav files to ogg files.

Debian Linux Security Advisory 5511-1 - Several security vulnerabilities have been discovered in mosquitto, a MQTT compatible message broker, which may be abused for a denial of service attack.

Debian Linux Security Advisory 5510-1 - Clement Lecigne discovered a heap-based buffer overflow in libvpx, a multimedia library for the VP8 and VP9 video codecs, which may result in the execution of arbitrary code if a specially crafted VP8 media stream is processed.

Debian Linux Security Advisory 5509-1 - A buffer overflow in VP8 media stream processing has been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code.

Debian Linux Security Advisory 5508-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Hello everyone! On the last day of September, I decided to record another retrospective episode on how my Vulnerability Management month went. Alternative video link (for Russia): https://vk.com/video-149273431_456239136 September was quite a busy month for me. Vulnerability Management courses I participated in two educational activities. The first one is an on-line cyber security course for […]
