| VAR-202101-1926 | CVE-2021-3156 | Sudo Buffer error vulnerability | 
                                      
                                        CVSS V2: 7.2 CVSS V3: 7.8 Severity: HIGH  | 
                            Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. Any local user (sudoers and non-sudoers)
can exploit this flaw for root privilege escalation. 
For the stable distribution (buster), this problem has been fixed in
version 1.8.27-1+deb10u3. 
We recommend that you upgrade your sudo packages.

Several vulnerabilities were discovered in OpenLDAP, a free
implementation of the Lightweight Directory Access Protocol. An
unauthenticated remote attacker can take advantage of these flaws to
cause a denial of service (slapd daemon crash, infinite loops) via
specially crafted packets. 
For the stable distribution (buster), these problems have been fixed in
version 2.4.47+dfsg-3+deb10u5. 
We recommend that you upgrade your openldap packages

Several vulnerabilities were discovered in OpenLDAP, a free
implementation of the Lightweight Directory Access Protocol. An
unauthenticated remote attacker can take advantage of these flaws to
cause a denial of service (slapd daemon crash, infinite loops) via
specially crafted packets. 
For the stable distribution (buster), these problems have been fixed in
version 2.4.47+dfsg-3+deb10u5. 
We recommend that you upgrade your openldap packages

Several vulnerabilities were discovered in OpenLDAP, a free
implementation of the Lightweight Directory Access Protocol. An
unauthenticated remote attacker can take advantage of these flaws to
cause a denial of service (slapd daemon crash, infinite loops) via
specially crafted packets. 
For the stable distribution (buster), these problems have been fixed in
version 2.4.47+dfsg-3+deb10u5. 
We recommend that you upgrade your openldap packages

                            An integer underflow was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Certificate List Exact Assertion processing, resulting in denial of service. OpenLDAP Exists in an integer underflow vulnerability.Denial of service (DoS) It may be put into a state. Pillow is a Python-based image processing library. 
There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. There is a denial of service vulnerability in OpenLDAP versions prior to 2.4.57. -----BEGIN PGP SIGNED MESSAGE-----

The static IP configuration from QR code is copied to the file /config/ip-static and after reboot data from this file is inserted into bash command (without any escaping). So bash injection is possible. Camera doesn't parse QR codes if it's already successfully configured. Camera is always rebooted after successful configuration via QR code. Rostelecom CS-C2SHW Has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state

                            Heap overflow with full parsing of HTTP respose in Rostelecom CS-C2SHW 5.0.082.1. AgentUpdater service has a self-written HTTP parser and builder. HTTP parser has a heap buffer overflow (OOB write). In default configuration camera parses responses only from HTTPS URLs from config file, so vulnerable code is unreachable and one more bug required to reach it. Rostelecom CS-C2SHW Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state
