Description
This security bulletin contains information about 1 vulnerability.
1) Buffer overflow (CVE-ID: CVE-2015-3281)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The buffer_slow_realign function in HAProxy 1.5.x before 1.5.14 and 1.6-dev does not properly realign a buffer that is used for pending outgoing data, which allows remote attackers to obtain sensitive information (uninitialized memory contents of previous requests) via a crafted request.
