Package : ruby-websocket-extensions Version : 0.1.2-1+deb9u1 CVE ID : CVE-2020-7663 Debian Bug : #964274 It was discovered that there was a denial of service vulnerability in ruby-websocket-extensions, a library for managing long-lived HTTP "WebSocket" connections. The parser took quadratic time when parsing a header containing an unclosed string parameter value whose content is a repeating two-byte sequence. This could be abused by an attacker to conduct a Regex Denial Of Service (ReDoS) on a single-threaded server by providing a malicious payload in the Sec-WebSocket-Extensions HTTP header. For Debian 9 "Stretch", this problem has been fixed in version 0.1.2-1+deb9u1. We recommend that you upgrade your ruby-websocket-extensions packages. For the detailed security status of ruby-websocket-extensions please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ruby-websocket-extensions Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAl89FAQACgkQHpU+J9Qx HlikkxAAlorJXcUDFa7s/SAVRsb0HT0rWRmXFqSSr2GIQ6n8mJteprBdu6ueMgge FQnai6Bbp4gM9iNwSm64jUvMHv+XoXXWy/LAhT9kKRNkKK2h/KpBFz+sdDeXZRTD 5NgKrnUA/j00zk5Q5zQM9wO4pRKHxAuv5ireogqzcAfBOHAL9kSg725pVmf8Z1iy 5UnivwBgV5Rp44iUKlZML46tP3LztvwylyZ40NlQ711CUcVNLOzIddNsxM1ZRwkW 2INjklMenTilfsWUJGk0XsUSdhekXa3aOW48J7ZTvWcmrla2XA3mMFS6g6jnb73y JBQSmREUtESGwqg8T+60HQvi78ijPhgWRbatMajCaq7iEicQiACrq3lUe80yHHkK HYW7BO0OeQkPX5bxyjk8B9H0i+VOaRUQGcuh/Ylzzbp3yW/Ht1ym0ntjwWhejmtC +Um7BJi6FAEUNUzrb/H1EpoOqsbAc//kPY8qpkhNBEm0xO+RinPILmWKapqJkmds aMNswFtTBXc0jO9kCxZxBaSZFGRs4AMWTkvOrrXNKR06z1PxX5ZRDpkHkdIv3R/W 6dHEaKx3oTi5Yz3tvDCKzA6P5d0/HYCiKdsksKFOT58KpjdxiTvplioQ6fesoHZJ mPYLryHI8W3WcxmRpAl7GZXjfFpBGtqcK+vBQ1ujmzH1Jm5TcZY= =2I5N -----END PGP SIGNATURE-----
