CVE-2024-45506 1 Haproxy 1 Haproxy 2024-09-09 7.5 High
HAProxy 2.9.x before 2.9.10, 3.0.x before 3.0.4, and 3.1.x through 3.1-dev6 allows a remote denial of service.
CVE-2012-2942 1 Haproxy 1 Haproxy 2024-08-06 N/A
Buffer overflow in the trash buffer in the header capture functionality in HAProxy before 1.4.21, when global.tune.bufsize is set to a value greater than the default and header rewriting is enabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors.
CVE-2013-2175 4 Canonical, Debian, Haproxy and 1 more 6 Ubuntu Linux, Debian Linux, Haproxy and 3 more 2024-08-06 N/A
HAProxy 1.4 before 1.4.24 and 1.5 before 1.5-dev19, when configured to use hdr_ip or other "hdr_*" functions with a negative occurrence count, allows remote attackers to cause a denial of service (negative array index usage and crash) via an HTTP header with a certain number of values, related to the MAX_HDR_HISTORY variable.
CVE-2013-1912 2 Haproxy, Redhat 3 Haproxy, Enterprise Linux, Openshift 2024-08-06 N/A
Buffer overflow in HAProxy 1.4 through 1.4.22 and 1.5-dev through 1.5-dev17, when HTTP keep-alive is enabled, using HTTP keywords in TCP inspection rules, and running with rewrite rules that appends to requests, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted pipelined HTTP requests that prevent request realignment from occurring.
CVE-2014-6269 2 Haproxy, Redhat 2 Haproxy, Enterprise Linux 2024-08-06 N/A
Multiple integer overflows in the http_request_forward_body function in proto_http.c in HAProxy 1.5-dev23 before 1.5.4 allow remote attackers to cause a denial of service (crash) via a large stream of data, which triggers a buffer overflow and an out-of-bounds read.
CVE-2015-3281 6 Canonical, Debian, Haproxy and 3 more 14 Ubuntu Linux, Debian Linux, Haproxy and 11 more 2024-08-06 N/A
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.
CVE-2016-5360 2 Canonical, Haproxy 2 Ubuntu Linux, Haproxy 2024-08-06 N/A
HAproxy 1.6.x before 1.6.6, when a deny comes from a reqdeny rule, allows remote attackers to cause a denial of service (uninitialized memory access and crash) or possibly have unspecified other impact via unknown vectors.
CVE-2016-2102 1 Haproxy 1 Haproxy 2024-08-05 N/A
HAProxy statistics in openstack-tripleo-image-elements are non-authenticated over the network.
CVE-2018-20615 4 Canonical, Haproxy, Opensuse and 1 more 7 Ubuntu Linux, Haproxy, Leap and 4 more 2024-08-05 N/A
An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.
CVE-2018-20102 3 Canonical, Haproxy, Redhat 5 Ubuntu Linux, Haproxy, Openshift and 2 more 2024-08-05 N/A
An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.
CVE-2018-20103 3 Canonical, Haproxy, Redhat 5 Ubuntu Linux, Haproxy, Openshift and 2 more 2024-08-05 N/A
An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion.
CVE-2018-14645 3 Canonical, Haproxy, Redhat 6 Ubuntu Linux, Haproxy, Enterprise Linux and 3 more 2024-08-05 N/A
A flaw was discovered in the HPACK decoder of HAProxy, before 1.8.14, that is used for HTTP/2. An out-of-bounds read access in hpack_valid_idx() resulted in a remote crash and denial of service.
CVE-2018-11469 3 Canonical, Haproxy, Redhat 3 Ubuntu Linux, Haproxy, Rhel Software Collections 2024-08-05 N/A
Incorrect caching of responses to requests including an Authorization header in HAProxy 1.8.0 through 1.8.9 (if cache enabled) allows attackers to achieve information disclosure via an unauthenticated remote request, related to the proto_http.c check_request_for_cacheability function.
CVE-2018-10184 2 Haproxy, Redhat 4 Haproxy, Enterprise Linux, Openshift and 1 more 2024-08-05 N/A
An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the max_frame_size setting instead of being checked against the bufsize. The max_frame_size only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the SETTINGS frame, a wrapped frame will be defragmented into a temporary allocated buffer where the second fragment may overflow the heap by up to 16 kB. It is very unlikely that this can be exploited for code execution given that buffers are very short lived and their addresses not realistically predictable in production, but the likelihood of an immediate crash is absolutely certain.
CVE-2019-19330 4 Canonical, Debian, Haproxy and 1 more 6 Ubuntu Linux, Debian Linux, Haproxy and 3 more 2024-08-05 9.8 Critical
The HTTP/2 implementation in HAProxy before 2.0.10 mishandles headers, as demonstrated by carriage return (CR, ASCII 0xd), line feed (LF, ASCII 0xa), and the zero character (NUL, ASCII 0x0), aka Intermediary Encapsulation Attacks.
CVE-2019-18277 2 Haproxy, Redhat 4 Haproxy, Enterprise Linux, Openshift and 1 more 2024-08-05 7.5 High
A flaw was found in HAProxy before 2.0.6. In legacy mode, messages featuring a transfer-encoding header missing the "chunked" value were not being correctly rejected. The impact was limited but if combined with the "http-reuse always" setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).
CVE-2019-14243 1 Haproxy 1 Proxyprotocol 2024-08-05 7.5 High
headerv2.go in mastercactapus proxyprotocol before 0.0.2, as used in the mastercactapus caddy-proxyprotocol plugin through 0.0.2 for Caddy, allows remote attackers to cause a denial of service (webserver panic and daemon crash) via a crafted HAProxy PROXY v2 request with truncated source/destination address data.
CVE-2019-14241 1 Haproxy 1 Haproxy 2024-08-05 N/A
HAProxy through 2.0.2 allows attackers to cause a denial of service (ha_panic) via vectors related to htx_manage_client_side_cookies in proto_htx.c.
CVE-2019-11323 1 Haproxy 1 Haproxy 2024-08-04 5.9 Medium
HAProxy before 1.9.7 mishandles a reload with rotated keys, which triggers use of uninitialized, and very predictable, HMAC keys. This is related to an include/types/ssl_sock.h error.
CVE-2020-11100 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2024-08-04 8.8 High
In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution.
