Debian 9 DLA-2588-1 Critical: Zeromq3 Memory Leak And Heap Overflow

Two security issues have been detected in zeromq3. CVE-2021-20234 . - ------------------------------------------------------------------------- Debian LTS Advisory DLA-2588-1 This email address is being protected from spambots. You need JavaScript enabled to view it. https://www.debian.org/lts/security/ Anton Gladky March 09, 2021 https://wiki.debian.org/LTS - ------------------------------------------------------------------------- Package : zeromq3 Version : 4.2.1-4+deb9u4 CVE ID : CVE-2021-20234 CVE-2021-20235 Two security issues have been detected in zeromq3. CVE-2021-20234 Memory leak in client induced by malicious server(s) without CURVE/ZAP. From issue description [1]. When a pipe processes a delimiter and is already not in active state but still has an unfinished message, the message is leaked. CVE-2021-20235 Heap overflow when receiving malformed ZMTP v1 packets. From issue description [2]. The static allocator was implemented to shrink its recorded size similarly to the shared allocator. But it does not need to, and it should not, because unlike the shared one the static allocator always uses a static buffer, with a size defined by the ZMQ_IN_BATCH_SIZE socket option (default 8192), so changing the size opens the library to heap overflows. The static allocator is used only with ZMTP v1 peers.

We recommend that you upgrade your zeromq3 packages.
