CVE-2012-2841
HighSummary
W bibliotece libexif w wersji 0.6.20 występuje błąd przepełnienia bufora na stercie spowodowany niedoborem wartości całkowitej w funkcji exif_entry_get_value. Atakujący mogą wykorzystać ten błąd, przesyłając odpowiednio skonstruowany parametr rozmiaru bufora podczas formatowania tagu EXIF.
Risk Assessment
Podatność ta może umożliwić zdalnym atakującym wykonanie dowolnego kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemów korzystających z tej biblioteki. Może to prowadzić do przejęcia kontroli nad systemem lub wycieku danych.
Recommendation
Zaleca się aktualizację biblioteki libexif do najnowszej wersji, aby usunąć tę podatność. Należy również monitorować systemy pod kątem nieautoryzowanych działań i potencjalnych exploitów.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.

Cotonti 1.0.0 Comments plugin passes the ci GET parameter to unserialize() without allowed_classes restriction, allowing unauthenticated attackers to instantiate arbitrary PHP classes with attacker-controlled properties. Attackers can exploit PHP object injection through crafted serialized payloads to trigger gadget chains and achieve database manipulation or code execution.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Versions prior to 2.1.30 expose the Streamable HTTP MCP endpoint without an effective Host or Origin allowlist. A malicious web page can use DNS rebinding to route browser requests to a victim's local MCP listener while preserving an attacker-controlled `Host` and `Origin`.
Original NVD description (English source)
Integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) 0.6.20 might allow remote attackers to execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
