Debian Security Advisory 5411-1

Perfctl malware is hard to detect, persists after reboots, and can perform a breadth of malicious activities.

New Linux malware ‘Perfctl’ is targeting millions worldwide, mimicking system files to evade detection. This sophisticated malware compromises…

Linux servers are the target of an ongoing campaign that delivers a stealthy malware dubbed perfctl with the primary aim of running a cryptocurrency miner and proxyjacking software. "Perfctl is particularly elusive and persistent, employing several sophisticated techniques," Aqua security researchers Assaf Morag and Idan Revivo said in a report shared with The Hacker News. "When a new user logs

Armed with a staggering arsenal of at least 20,000 different exploits for various Linux server misconfigurations, perfctl is everywhere, annoying, and tough to get rid of.

Internet-exposed Selenium Grid instances are being targeted by bad actors for illicit cryptocurrency mining and proxyjacking campaigns. "Selenium Grid is a server that facilitates running test cases in parallel across different browsers and versions," Cado Security researchers Tara Gould and Nate Bill said in an analysis published today. "However, Selenium Grid's default configuration lacks

A vendor honeypot caught two attacks intended to leverage the tens of thousands of exposed Selenium Grid Web app testing servers.

Integer Overflow or Wraparound in GitHub repository gpac/gpac prior to 2.1-DEV.

The gf_hinter_track_finalize function in GPAC 1.0.1 allows attackers to cause a denial of service via a crafted file in the MP4Box command.

The gf_bs_write_data function in GPAC 1.0.1 allows attackers to cause a denial of service via a crafted file in the MP4Box command.

The GetHintFormat function in GPAC 1.0.1 allows attackers to cause a denial of service via a crafted file in the MP4Box command.

In GPAC MP4Box 1.1.0, there is a Null pointer reference in the function gf_filter_pid_get_packet function in src/filter_core/filter_pid.c:5394, as demonstrated by GPAC. This can cause a denial of service (DOS).

Use After Free in GitHub repository gpac/gpac prior to v2.1.0-DEV.

MP4Box is a component of GPAC-2.0.0, which is a widely-used third-party package on RPM Fusion. When MP4Box tries to parse a MP4 file, it calls the function `diST_box_read()` to read from video. In this function, it allocates a buffer `str` with fixed length. However, content read from `bs` is controllable by user, so is the length, which causes a buffer overflow.

GPAC mp4box 1.1.0-DEV-rev1727-g8be34973d-master has a stack-overflow vulnerability in function gf_isom_get_sample_for_movie_time of mp4box.

GPAC 1.0.1 is affected by a NULL pointer dereference in gf_utf8_wcslen. (gf_utf8_wcslen is a renamed Unicode utf8_wcslen function.)

Multiple exploitable integer overflow vulnerabilities exist within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. A specially crafted MPEG-4 input can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. An attacker can convince a user to open a video to trigger this vulnerability.
