TITLE

Brotli  Classic buffer overflow vulnerability in library

DESCRIPTION

A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits. Brotli A classic buffer overflow vulnerability exists in the library.Information is tampered with and denial of service (DoS) It may be put into a state. For the stable distribution (buster), this problem has been fixed in version 1.0.7-2+deb10u1. We recommend that you upgrade your brotli packages. For the detailed security status of brotli please refer to its security tracker page at: https://security-tracker.debian.org/tracker/brotli 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----- iQIzBAEBCgAdFiEEtuYvPRKsOElcDakFEMKTtsN8TjYFAl/GuhkACgkQEMKTtsN8 TjZ68A/9ED9ToGA8pwsL99uHc4FA6EBIKzPDIz4I649PTvrKi8wpfa6RqrcfhcCE xfOx4+PiYaUqOnAy02O0cbkvzQvcGIVlrIxJ0v4/QFAbiuX5Gy/q9b3ZkHsIRybK +PywHjHEKBqwR9vetV1xYM8s4Smh6iwH+UjHxt9E0/KEHWQF17N094yubtrIJrDf irZDMFnXYCeWRrAZH5rwB6Be6X0nQri3WF9vcdBK61vktSv+iTVklCNbIKrQr1p8 SHPIlUBIp/LjeHaSq+ZNYzSwg1LVtGKqwlvWaRbiBY3Uf5VYyXVKRL7m8WDR7ozu GnfIpBnfttx2sptBAAq8OFx9hmzFEGVSfNy5sXbhb9HoUjX2URUUzN+1z71Da6Tz XrMgJlJ9YQrDAV0dpakztVdSbWV9Ub3bS3Jth3L42dsJGA7qyfs3KmsnkNJj5x3L dHQl6VZRxvUpsHE9zyKAN/rnPyvcrloZ04qxWtJKcvR113mFTlehKDTNjWzCnSic Knzzl/ArWjyNFQ+1kNwXbMSSIOvgBHYSwQI8rqjvaR33jk+P1Mt41VRzdwmT6t5c 4c85j18OrBdAfu1E7Fqy3MAeZq7dRR0prQzVAvxzUXgu/4G8nCvRbW6MDt2scnR0 BYT1fKy//PWHKdNzOMdjbE6Ab6rX0DbaNfHgpjsD2r0VYSv7W/E= =mzSF -----END PGP SIGNATURE----- .
