Package : python-html-sanitizer Version : 1.9.1-2+deb11u1 CVE ID : CVE-2024-34078 Debian Bug : 1070710 It was discovered that there was a sanitisation bypass issue in python-html-sanitizer, a library used ensure that user-specified content cannot inject HTML or JavaScript into a webpage. If the default "keep_typographic_whitespace=False" value was set, malicous users could have exploited the fact that some Unicode characters normalise to chevrons, which allowed specially-crafted HTML to escape sanitization. For Debian 11 bullseye, this problem has been fixed in version 1.9.1-2+deb11u1. We recommend that you upgrade your python-html-sanitizer packages. For the detailed security status of python-html-sanitizer please refer to its security tracker page at: https://security-tracker.debian.org/tracker/python-html-sanitizer 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+J9QxHlgFAmbModMACgkQHpU+J9Qx HljLvhAAriMt4e8j+vTlDJzh+eaNhfcGNhetCdeQBvhy0W80eFs3znusramI3A/s R1TIrj8fOhWg9NMLwwUs9/OHHAtGUEIrmluj8RfQD4cMOKjWbDXgnxqNQzg1+njD ZLnO3OvMAneXz52C4A5ts47RGJswhFASEd2WHCpsH5FjtbzqQDRe/auVjOe4Lf3v Fk8Fo4Y98M4JBfPKOGECXajjUvhSSuhKCVURiybkqoc9RCVocBy/8ukG8lfB8Bhe zRz9/Dfbj/Ftljgg4LDuYvA0x5vQR5d4MPl5R/ON/vS7RlkW8LUL1eyLpjdZyj1I Pg3ihhg0gzXFPCYMNQmLxsnDfWSTBahXtSxNw81+SPwd/IBi6OE9pTSP/tgGu6oI dCti9nzeglNqtakLthtq13UklDrD9MqgZoRmNnVgTdyHPgas3ZL8qbzQbrZJSFvs tLhnLwNm+ASECbKcceJxiT11Yyn6pn0j4MCCg5xw99cCcnh9DawCcfXJ2DF/oipZ aEP0G0Gs7eFsPi2nVVVQfZARfenN71mtiPTGkZ5whSyhZT8/QbrRKEjpexLqgMmg VeqTbKkxSTECC7rJtneq7/dZXDdobsveuRfcmwK9btwGpiqPUot5CqjuT0e8lzPV O5iRTL5EONTqt6kJMK3t6myy6MGZYBHfDbfYVzi+tIBtPNWMcoQ= =QfUA -----END PGP SIGNATURE-----
