*** Pendiente de traducción *** Aria Operations for Networks contains an Authentication Bypass vulnerability due to a lack of unique cryptographic key generation. A malicious actor with network access to Aria Operations for Networks could bypass SSH authentication to gain access to the Aria Operations for Networks CLI.

*** Pendiente de traducción *** goauthentik is an open-source Identity Provider. In affected versions using a recovery flow with an identification stage an attacker is able to determine if a username exists. Only setups configured with a recovery flow are impacted by this. Anyone with a user account on a system with the recovery flow described above is susceptible to having their username/email revealed as existing. An attacker can easily enumerate and check users' existence using the recovery flow, as a clear message is shown when a user doesn't exist. Depending on configuration this can either be done by username, email, or both. This issue has been addressed in versions 2023.5.6 and 2023.6.2. Users are advised to upgrade. There are no known workarounds for this issue.

*** Pendiente de traducción *** OpenPGP.js is a JavaScript implementation of the OpenPGP protocol. In affected versions OpenPGP Cleartext Signed Messages are cryptographically signed messages where the signed text is readable without special tools. These messages typically contain a "Hash: ..." header declaring the hash algorithm used to compute the signature digest. OpenPGP.js up to v5.9.0 ignored any data preceding the "Hash: ..." texts when verifying the signature. As a result, malicious parties could add arbitrary text to a third-party Cleartext Signed Message, to lead the victim to believe that the arbitrary text was signed. A user or application is vulnerable to said attack vector if it verifies the CleartextMessage by only checking the returned `verified` property, discarding the associated `data` information, and instead _visually trusting_ the contents of the original message. Since `verificationResult.data` would always contain the actual signed data, users and apps that check this information are not vulnerable. Similarly, given a CleartextMessage object, retrieving the data using `getText()` or the `text` field returns only the contents that are considered when verifying the signature. Finally, re-armoring a CleartextMessage object (using `armor()` will also result in a "sanitised" version, with the extraneous text being removed. This issue has been addressed in version 5.10.1 (current stable version) which will reject messages when calling `openpgp.readCleartextMessage()` and in version 4.10.11 (legacy version) which will will reject messages when calling `openpgp.cleartext.readArmored()`. Users are advised to upgrade. Users unable to upgrade should check the contents of `verificationResult.data` to see what data was actually signed, rather than visually trusting the contents of the armored message.

Se ha descubierto que AOMedia v3.0.0 a v3.5.0 contiene un acceso no válido a la memoria de lectura a través del componente "assign_frame_buffer_p in av1/common/av1_common_int.h. ".

*** Pendiente de traducción *** On affected platforms running Arista EOS with mirroring to multiple destinations configured, an internal system error may trigger a kernel panic and cause system reload.<br />

*** Pendiente de traducción *** Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor&amp;#39;s position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input.

*** Pendiente de traducción *** A heap-based buffer overflow exists in the qr_reader_match_centers function of ZBar 0.23.90. Specially crafted QR codes may lead to information disclosure and/or arbitrary code execution. To trigger this vulnerability, an attacker can digitally input the malicious QR code, or prepare it to be physically scanned by the vulnerable scanner.

*** Pendiente de traducción *** A stack-based buffer overflow vulnerability exists in the lookup_sequence function of ZBar 0.23.90. Specially crafted QR codes may lead to information disclosure and/or arbitrary code execution. To trigger this vulnerability, an attacker can digitally input the malicious QR code, or prepare it to be physically scanned by the vulnerable scanner.

*** Pendiente de traducción *** On affected platforms running Arista EOS with VXLAN configured, malformed or truncated packets received over a VXLAN tunnel and forwarded in hardware can cause egress ports to be unable to forward packets. The device will continue to be susceptible to the issue until remediation is in place.<br />

MyBB anterior a 1.8.36 permite la inyección de código por parte de usuarios con ciertos privilegios elevados. Las plantillas en Admin CP usan intencionalmente eval, y hubo cierta validación de la entrada para eval, pero el malabarismo de tipos interfirió con esto cuando se usaba PCRE dentro de PHP.<br />

*** Pendiente de traducción *** Nokia Service Router Operating System (SR OS) 22.10 and SR Linux, when error-handling update-fault-tolerance is not enabled, mishandle BGP path attributes.

FRRouting FRR 7.5.1 a 9.0 y Pica8 PICOS 4.3.3.2 permiten a un atacante remoto causar una denegación de servicio a través de una actualización BGP manipulada con un atributo dañado 23 (encapsulación de túnel).
