| Doc Text: |
A flaw was found in the HAProxy. This issue can allow a buffer overflow via improper length checking when replacing multiple regex back-references in a string. Specifically, the replacement size is incorrectly validated against the output buffer instead of the temporary trash buffer used during substitution. If multiple matches are replaced with strings larger than the available buffer size, this can lead to a memory overwrite.
