 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4387-1 [email protected] https://www.debian.org/lts/security/ Sylvain Beucler November 29, 2025 https://wiki.debian.org/LTS

 Package : qtbase-opensource-src Version : 5.15.2+dfsg-9+deb11u2 CVE ID : CVE-2024-39936 Debian Bug : 1076293

 A race condition was discovered in Qt, a cross-platform C++ application framework. Code to make security-relevant decisions about an established HTTP2 connection may execute too early, because the encrypted() signal has not yet been emitted and processed.

 For Debian 11 bullseye, this problem has been fixed in version 5.15.2+dfsg-9+deb11u2.

 We recommend that you upgrade your qtbase-opensource-src packages.

 For the detailed security status of qtbase-opensource-src please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/qtbase-opensource-src

 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

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libqt5concurrent5 packages.
