ELTS report November 2023 ========================= 1. ELA-1001-1. Issued a security update for postgresql-9.6 fixing 4 CVE in Stretch. This update included the fix for CVE-2023-39417 which I have been working on in October and three new CVE published at the beginning of November. 2. ELA-1003-1. Issued a security update for postgresql-9.4 fixing 2 CVE in Jessie. This update included the fix for CVE-2023-39417 which I have been working on in October and the fix for one new CVE, CVE-2023-5869. I triaged CVE-2023-5868 as not-affected and CVE-2023-5870 as no-dsa because it was a minor issue and only exploitable in a unlikely rare edge case. 3. Netty: I marked CVE-2023-44487 in Stretch as ignored because in order to properly fix this problem we would have to backport the whole codec-http2 module from Buster at the minimum. Everything else would not have addressed the problem completely since other issues like CVE-2021-21409 and CVE-2021-21295 were already ignored. A simple workaround exists by switching to HTTP/1 instead. 4. I have been ELTS frontdesk from 13.11.2023 to 19.11.2023 and triaged newly discovered CVE in supported packages. 5. GnuTLS: I investigated CVE-2023-5981 and decided to mark Jessie and Stretch as ignored. The patch to fix CVE-2023-5981 relies on a new function, gnutls_privkey_decrypt_data2, first introduced in version 3.6.5. This may break existing applications. Timing attack vulnerabilities are usually hard to exploit because the measurement of those differences depends on several factors like processor architecture, algorithms used, accuracy of the measurement, etc. 6. ELA-1008-1. Issued a security update for audiofile fixing 2 CVE in Stretch. I reviewed the patches prepared by Bastien Roucaries. 7. ELA-1009-1. Issued a security update for symfony fixing 1 CVE in Stretch. 8. ELA-1018-1. Issued a security update for rabbbitmq-server fixing 1 CVE in Stretch. 9. Bouncycastle,CVE-2023-33202: I investigated the impact of a potential denial of service attack and contacted the upstream developers for further information. The investigation has not been concluded yet. 10. I have been working on a security update of squid3 in Jessie and Stretch. and investigated the currently six open CVE. The work on these problems is still ongoing.
