CVE-2012-2110
HighSummary
Funkcja asn1_d2i_read_bio w OpenSSL przed wersją 0.9.8v, 1.0.0 przed 1.0.0i oraz 1.0.1 przed 1.0.1a nieprawidłowo interpretuje dane całkowite, co umożliwia zdalnym atakującym przeprowadzenie ataków typu buffer overflow. Może to prowadzić do awarii usługi (uszkodzenia pamięci) lub innych nieokreślonych skutków.
Risk Assessment
Podatność ta stwarza ryzyko dla organizacji, umożliwiając zdalnym atakującym przeprowadzenie ataków, które mogą prowadzić do awarii systemu lub innych poważnych problemów z bezpieczeństwem.
Recommendation
Zaleca się aktualizację OpenSSL do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia potencjalnych prób ataków.

Improper input validation in the network communication processing in NEC WebSAM WinShare versions 7.2.0 through 7.5.0, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary commands with SYSTEM privileges via a crafted network packet sent to the computer running WinShare.
- CVE-2026-124560Critical
A vulnerability was found in D-Link DIR-878 version 1.20B05 in the GetCAPTCHAsetting function of bin/prog.cgi (HNAP Handler component). Manipulating the uid argument results in a heap-based buffer overflow. The attack can be initiated remotely and the exploit has been made public.
- CVE-2026-119506Critical
The Frontend Admin by DynamiApps plugin (acf-frontend-form-element) through version 3.30.1 contains an incorrect privilege assignment vulnerability. The flaw allows an attacker to escalate privileges within the WordPress site.
- CVE-2026-6715Critical
IBM Concert 1.0 through 3.0.1.1 allows an attacker to supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.
- CVE-2026-17466Critical
IBM Optim versions 1.0.0, 1.1.0, and 1.2.0 are vulnerable to path traversal, allowing a remote authenticated attacker to obtain sensitive information.
- CVE-2026-15266Critical
IBM Concert 1.0 through 3.0.1.1 contains components that allow potentially unsafe command execution, which could be exploited to run arbitrary system commands on the host.
- CVE-2026-114464Critical
IBM Process Mining 2.0.0 through 2.2.1 has improper access control, which could allow a remote attacker to obtain sensitive information.
- CVE-2026-107331Critical
IBM DataStage on Cloud Pak for Data 5.4.0.0 has an absolute-path traversal vulnerability that could allow a remote authenticated attacker to obtain sensitive information.
- CVE-2026-109900Critical
The Melapress Role Editor plugin for WordPress (through version 1.3.0) contains an incorrect privilege assignment vulnerability that allows privilege escalation. A low-privileged user can gain a higher level of access within the system.
Original NVD description (English source)
The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key.
