[ruby-core:63737] [ruby-trunk - Bug #10019] segmentation fault/buffer overrun in pack.c (encodes)

Issue #10019 has been updated by Ramon de C Valle. It seems that the (off-by-one) issue is also present in Ruby 1.9.3, requiring a backport too. It may also worth confirming with the reporter if he continues to observe the crash after adding the fix, since as Tomas analysis of aws-sdk gem and its dependencies indicates it's unlikely this issue is being caused by any of these gems. So, it may be the case the reporter may be referring to a different issue. ---------------------------------------- Bug #10019: segmentation fault/buffer overrun in pack.c (encodes) https://bugs.ruby-lang.org/issues/10019#change-47781 * Author: Will Wood * Status: Closed * Priority: Low * Assignee: * Category: core * Target version: * ruby -v: ruby 2.1.2p168 (2014-07-06 revision 46721) [i386-mingw32] * Backport: 2.0.0: REQUIRED, 2.1: DONE ---------------------------------------- While working with an AWS sample I hit a segmentation fault. The same sample works under 1.9.3. It appeared to be coming from pack.c function encodes. After looking at the source there's a 4K buffer allocated on the stack. I made a minor change to base the buffer length off of the incoming buffer length with a pad and allocate it off the heap. Anyway, after fixing this my code sample runs fine. I'm including a patch file and the sample code. ---Files-------------------------------- pack.patch (2.74 KB) BucketTest.rb (326 Bytes) -- https://bugs.ruby-lang.org/
