A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nano_memalign, nano_valloc, nano_pvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow.
CWE-120
CVE-2021-34236
Buffer Overflow in Netgear R8000 Router with firmware v1.0.4.56 allows remote attackers to execute arbitrary code or cause a denial-of-service by sending a crafted POST to ‘/bd_genie_create_account.cgi’ with a sufficiently long parameter ‘register_country’.
CVE-2021-34055
jhead 3.06 is vulnerable to Buffer Overflow via exif.c in function Put16u.
CVE-2021-33897
A buffer overflow in Synthesia before 10.7.5567, when a non-Latin locale is used, allows user-assisted attackers to cause a denial of service (application crash) via a crafted MIDI file with malformed bytes. This file is mishandled during a deletion attempt. In Synthesia before 10.9, an improper path handling allows local attackers to cause a denial of service (application crash) via a crafted MIDI file with malformed bytes.
CVE-2021-33680
SAP 3D Visual Enterprise Viewer, version – 9, allows a user to open manipulated CGM file received from untrusted sources which causes buffer overflow and causes the application to crash and becoming temporarily unavailable until the user restarts the application.
CVE-2021-33719
A vulnerability has been identified in SIPROTEC 5 relays with CPU variants CP050 (All versions < V8.80), SIPROTEC 5 relays with CPU variants CP100 (All versions < V8.80), SIPROTEC 5 relays with CPU variants CP300 (All versions < V8.80). Specially crafted packets sent to port 4443/tcp could cause a Denial-of-Service condition or potential remote code execution.
