Title: openssl: EVP_EC_gen() segfault without init Status in openssl package in Ubuntu: In Progress Status in openssl source package in Jammy: Confirmed Status in openssl source package in Kinetic: In Progress Status in openssl package in Debian: Fix Released Bug description: [Impact] The fix for https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1968997 has broken some code paths as the new string comparison functions now need initialization, triggering segafults. The provided debdiff fixes the immediate issue and also settles on a new implementation not requiring the initialization in the first place. [Test Plan] Since this is a regression fix, we first need to check that the original bug hasn't cropped up again: sudo locale-gen tr_TR.UTF-8 LANG=C curl https://ubuntu.com/ > /dev/null # This work LANG=tr_TF.UTF-8 curl https://ubuntu.com/ > /dev/null # This should work as well For the regression itself: sudo apt install libssl-dev cat <<EOF > openssl_test.c #include <openssl/evp.h> int main() { EVP_PKEY_Q_keygen(NULL, NULL, "EC", "P-256"); } EOF gcc openssl_test.c -lcrypto -lssl -o openssl_test ./openssl_test [Where problems could occur] This new patch set is relatively massive, on top of another massive one. Some new regressions could crop up of a similar kind. Furthermore, the homegrown string comparison function could be buggy, leading to algorithm name mismatches. [Other info] The patches all come from upstream and have been merged on their 3.0 maintenance branch.
