Name of the Vulnerable Software and Affected Versions HAProxy versions 1.5.x through 1.5.13 HAProxy version 1.6-dev

Description The issue is related to the buffer slow realign function, which does not properly realign a buffer used for pending outgoing data. This allows remote attackers to obtain sensitive information, specifically uninitialized memory contents of previous requests, via a crafted request.

Recommendations For HAProxy versions 1.5.x through 1.5.13, update to version 1.5.14 or later. For HAProxy version 1.6-dev, consider disabling the buffer slow realign function until a patch is available. As a temporary workaround, restrict access to sensitive information to minimize the risk of exploitation.
