CVE-2007-5729
HighSummary
Emulator NE2000 w QEMU 0.8.2 pozwala lokalnym użytkownikom na wykonanie dowolnego kodu poprzez zapisanie ramek Ethernet o rozmiarze większym niż MTU do rejestru EN0_TCNT, co prowadzi do przepełnienia bufora na stercie w bibliotece slirp.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa systemu i danych organizacji.
Recommendation
Zaleca się aktualizację QEMU do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów pod kątem nieautoryzowanych działań.

- CVE-2026-53939Critical
In cjose versions 0.6.1 through 0.6.2.5, when encrypting a JWE using AES-CBC-HMAC content-encryption algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) with any key-management algorithm that generates a fresh content-encryption key (CEK), the CEK is all zero bytes instead of being randomly generated. The resulting JWE is encrypted and authenticated under a fixed, publicly known key, allowing anyone who obtains the JWE to recover plaintext and forge or modify content. Fixed in 0.6.2.6 by generating CEK from RAND_bytes.
- CVE-2026-53581Critical
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and write user-controlled data to any file.
- CVE-2026-85982Critical
The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host, could insert script content that executes in an administrator's browser.
Original NVD description (English source)
The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.
