CVE-2019-12527 – squid: heap-based buffer overflow in HttpHeader::getAuth
https://notcve.org/view.php?id=CVE-2019-12527
An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data. Se detectó un problema en Squid versiones 4.0.23 hasta 4.7. Al comprobar la autenticación básica con la función HttpHeader::getAuth, Squid utiliza un búfer global para almacenar los datos descodificados. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00056.html http://www.securityfocus.com/bid/109143 http://www.squid-cache.org/Versions/v4/changesets http://www.squid-cache.org/Versions/v4/changesets/squid-4-7f73e9c5d17664b882ed32590e6af310c247f320.patch https://access.redhat.com/errata/RHSA-2019:2593 https://github.com/squid-cache/squid/commits/v4 https://lists.fedoraproject.org/archives/list/package-announce%40li • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
