CVE-2010-2521
HighSummary
Wielokrotne przepełnienia bufora w pliku fs/nfsd/nfs4xdr.c w implementacji XDR w serwerze NFS w jądrze Linux przed wersją 2.6.34-rc6 mogą pozwolić zdalnym atakującym na spowodowanie odmowy usługi (panic) lub potencjalne wykonanie dowolnego kodu poprzez spreparowane żądanie WRITE NFSv4, związane z funkcjami read_buf i nfsd4_decode_compound.
Risk Assessment
Podatność ta stwarza ryzyko poważnych zakłóceń w działaniu systemu oraz możliwość zdalnego wykonania kodu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.34-rc6 lub nowszej, aby usunąć tę podatność oraz monitorowanie systemu pod kątem nieautoryzowanych prób dostępu.

Bifrost registers MCP clients through its management API, where a stdio client is a command plus args that is started immediately upon client addition, with no MCP handshake required. Authentication is disabled by default (governance.auth_config.is_enabled=false), meaning every caller is treated as a local admin. A single unauthenticated POST /api/mcp/client is enough to run a program as the Bifrost process user (appuser on the official image).

- CVE-2026-90693Critical
A flaw has been found in D-Link DIR-878 120B05 impacting the SetWan3Settings function of the WAN Settings component. Manipulation of the Primary/Secondary argument causes a stack-based buffer overflow. Remote exploitation of the attack is possible.
- CVE-2026-90692Critical
A vulnerability was detected in D-Link DIR-878 120B05 affecting the SetDynamicDNSIPv6Settings function of the Dynamic DNS IPv6 Settings component. Manipulation of the IPv6Address/Hostname argument results in a stack-based buffer overflow. The attack may be launched remotely.
- CVE-2026-85192Critical
The Joomla Conditional Content extension (regularlabs.com) in versions < 8.0.0 allows authenticated, privileged remote code execution. Conditional Content Pro accepts inline PHP Condition Rules in article syntax, and in affected versions the PHP is passed to the Conditions evaluator without checking who authored the article. Joomla's normal Author text filter preserves the syntax, so publishing the article causes the code to run as the web-server process.

A buffer overflow vulnerability was found in Totolink A3002MU version Hh-B20211125.1046, in the formPortFw function of /boafrm/formPortFw (boa component). Manipulating the service_type argument causes the overflow. The attack can be initiated remotely and the exploit has been published.
Original NVD description (English source)
Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions.
