Bug ID: 28470
Summary: Buffer read overrun in regular expression searching
Product: glibc
Version: 2.34
Status: NEW
Severity: normal
Priority: P2
Component: regex
Assignee: eggert at cs dot ucla.edu
Reporter: eggert at cs dot ucla.edu
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 13724

Patch glibc read buffer overrun in re_search_internal
The glibc regular expression matcher can overrun a read buffer when ignoring
case in a multibyte locale. Patch attached. I do not have a test case; I
suppose a test case could be derived from Benno's email, cited in the patch.

I installed the patch and am resolving the bug as fixed. Unfortunately I don't
have a test case (not always trivial for read overruns).
