Alvin ISD is a dynamic learning institution dedicated to serving all 252 square miles of our district. Visit our website for more information on our great district!
Second largest school district in the nation, LAUSD enrolls 640,000+ students in kindergarten through 12th grade, at over 900 schools, and 187 public charter schools. The boundaries spread over 720 square miles and include the mega-city of Los Angeles as well as all or parts of 31 smaller municipalities plus several unincorporated sections of Southern California. The mission of LAUSD is reflected in continued double-digit growth on the state Academic Performance Index (API); the upward trend in the graduation rate, progress in the pass rate on the California High School Exit Exam (CAHSEE) and other academic indicators. LA schools boast more winners of the United States Academic Decathlon championships-12-than any other District in this country. Add to those impressive victories, outstanding individual student and team achievements in: science, mathematics, social studies, language arts, foreign and dual languages, business and entrepreneurial skills, the visual and performing arts, and athletics. Nationally recognized by the Physicians Committee for Responsible Medicine for serving healthy, low fat and vegetarian school lunches. LAUSD's standards also call for: whole grains, low sodium, locally grown fruits and vegetables and no trans fat; flavored milk or carbonated beverages. Today, the District counts more than 115 new schools and campuses, thanks to the nation's largest public works project, funded by bond measures, a testament to broad voter support.

Sakai is a Collaboration and Learning Environment. Prior to versions 23.5 and 25.0, EncryptionUtilityServiceImpl initialized an AES256TextEncryptor password (serverSecretKey) using RandomStringUtils with the default java.util.Random. java.util.Random is a non‑cryptographic PRNG and can be predicted from limited state/seed information (e.g., start time window), substantially reducing the effective search space of the generated key. An attacker who can obtain ciphertexts (e.g., exported or at‑rest strings protected by this service) and approximate the PRNG seed can feasibly reconstruct the serverSecretKey and decrypt affected data. SAK-49866 is patched in Sakai 23.5, 25.0, and trunk.
pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream of a page using the LZWDecode filter. This has been fixed in pypdf version 6.1.3.
pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3.
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to version 1.6.5, Authlib’s JWE zip=DEF path performs unbounded DEFLATE decompression. A very small ciphertext can expand into tens or hundreds of megabytes on decrypt, allowing an attacker who can supply decryptable tokens to exhaust memory and CPU and cause denial of service. This issue has been patched in version 1.6.5. Workarounds for this issue involve rejecting or stripping zip=DEF for inbound JWEs at the application boundary, forking and add a bounded decompression guard via decompressobj().decompress(data, MAX_SIZE)) and returning an error when output exceeds a safe limit, or enforcing strict maximum token sizes and fail fast on oversized inputs; combine with rate limiting.
OpenBao is an open source identity-based secrets management system. Prior to version 2.4.2, OpenBao's audit log did not appropriately redact fields when relevant subsystems sent []byte response parameters rather than strings. This includes, but is not limited to sys/raw with use of encoding=base64, all data would be emitted unredacted to the audit log, and Transit, when performing a signing operation with a derived Ed25519 key, would emit public keys to the audit log. This issue has been patched in OpenBao 2.4.2.
