-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5009-1 security@debian.org https://www.debian.org/security/ Markus Koschany November 12, 2021 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : tomcat9 CVE ID : CVE-2021-42340 Apache Tomcat, the servlet and JSP engine, did not properly release an HTTP upgrade connection for WebSocket connections once the WebSocket connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError. For the stable distribution (bullseye), this problem has been fixed in version 9.0.43-2~deb11u3. We recommend that you upgrade your tomcat9 packages. For the detailed security status of tomcat9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/tomcat9 Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEErPPQiO8y7e9qGoNf2a0UuVE7UeQFAmGOe15fFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEFD RjNEMDg4RUYzMkVERUY2QTFBODM1RkQ5QUQxNEI5NTEzQjUxRTQACgkQ2a0UuVE7 UeRMcA/7BuGjRiyZnyDtGXxmq2Uew/62TR+u8WaZx6WC6mBNJgYvB1CHEap6+2EY YlFDiddqSC14tPAf+8gOWLVI1CzaWYtGYe8NjRpr6MjnUMfWonHnQn1SqDL8pORb yXLReYESx/YlvUs8+ZRsSoD5H0kFFA+6wYbeZ8gUcuyaV9hzRYDp3ATMAQCLL3RT obSBRpDv+0izjrCZqrcaLX0nBLK7YX/cEpGpT0xCqL6qkuDOVvLxtoc2HBCvYXsd i+9CL6sHzegCqzSypO+GTyOl815IF7BpqOTWm6JmqKDigQu6s432oT2o3Myex5+w CILS2jQaOLlf3nf9tGhbVDv6UougC27fXlkhopmBpINyKelX08Zazltsu86Wy2Zi O7eDLVQxeeSU7cgFBUoVwXouAG8vgfVw1cczYFE3O7Lj183pC3XS/HI+u3vGtooj LStn5jKDPI/vjAzaYk7sLH/OjDzmYXWX9/xQ0UpINK7I93CazE4toOjP0MlRMbZY MNm+KgKLD7ge1fzuZEyxmDempH5nsOcCz1I/xJ9O/gdpJOGAHg6Nu5FT+ceU6OeH lmY2BdUf46KYQO12wjs1VuapDwubiURGndA2F95aohxVV6QjsawKwJ9FLUKA+z6P TaTWS8DO8z9DAzA7IIAxuS9P0v4Hnr0L9ikldO1WMYQgOu5bLCI= =wISU -----END PGP SIGNATURE-----
