Package: libnss3
Version: 2:3.32-2
Severity: important
Even after the latest change, libnss3 on i386 still requires SSE2 to
run, because freebl's rijndael.c and gcm.c are still compiled with
-mclmul and -maes, which imply -msse2, and since these files contain
the software fallbacks, the generated code for fallbacks still uses
SSE2, which results in SIGILL on Pentium III and earlier.
The solution would be to use __attribute__((target)) for the functions
that need CLMUL and/or AES intrinsics instead of passing -mclmul and
-maes.
Top of stack after receiving SIGILL trying to run Firefox:
