Buffer overflow in cachemgr.cgi in Squid 2.x, 3.x before 3.5.17, and 4.x before 4.0.9 might allow remote attackers to cause a denial of service or execute arbitrary code by seeding manager reports with crafted data.
Due to buffer overflow issues Squid is vulnerable to a denial of service attack when processing ESI responses.
Due to incorrect input validation Squid is vulnerable to public information disclosure of the server stack layout when processing ESI responses.
Due to incorrect input validation and buffer overflow Squid is vulnerable to remote code execution when processing ESI responses.

Buffer overflow in Squid 3.x before 3.5.17 and 4.x before 4.0.9 allows remote attackers to execute arbitrary code via crafted Edge Side Includes (ESI) responses.
The strHdrAcptLangGetItem function in errorpage.cc in Squid 3.2.x before 3.2.9 and 3.3.x before 3.3.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a "," character in an Accept-Language header.
Double free vulnerability in Esi.cc in Squid 3.x before 3.5.18 and 4.x before 4.0.10 allows remote servers to cause a denial of service (crash) via a crafted Edge Side Includes (ESI) response.
clientsiderequest.cc in Squid 3.x before 3.5.18 and 4.x before 4.0.10 allows remote servers to cause a denial of service (crash) via crafted Edge Side Includes (ESI) responses.

The pinger in Squid 3.x before 3.4.8 allows remote attackers to obtain sensitive information or cause a denial of service (crash) via a crafted (1) ICMP or (2) ICMP6 packet size.
The pinger in Squid 3.x before 3.4.8 allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read and crash) via a crafted type in an (1) ICMP or (2) ICMP6 packet.
cachemgr.cgi in Squid 3.1.x and 3.2.x, possibly 3.1.22, 3.2.4, and other versions, allows remote attackers to cause a denial of service (resource consumption) via a crafted request. NOTE: this issue is due to an incorrect fix for CVE-2012-5643, possibly involving an incorrect order of arguments or incorrect comparison.
clientsiderequest.cc in Squid 3.2.x before 3.2.13 and 3.3.x before 3.3.8 allows remote attackers to cause a denial of service via a crafted port number in a HTTP Host header.
HttpHdrRange.cc in Squid 3.x before 3.3.12 and 3.4.x before 3.4.6 allows remote attackers to cause a denial of service (crash) via a request with crafted "Range headers with unidentifiable byte-range values."
Squid 3.x before 3.5.17 and 4.x before 4.0.9 allow remote attackers to obtain sensitive stack layout information via crafted Edge Side Includes (ESI) responses, related to incorrect use of assert and compiler optimization.
Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, do not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate.
