Описание
Squid is a web proxy cache. Starting in version 3.5.27 and prior to version 6.8, Squid may be vulnerable to a Denial of Service attack against HTTP Chunked decoder due to an uncontrolled recursion bug. This problem allows a remote attacker to cause Denial of Service when sending a crafted, chunked, encoded HTTP Message. This bug is fixed in Squid version 6.8. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. There is no workaround for this issue.
A flaw was found in Squid. This issue may allow a remote attacker to trigger an uncontrolled recursion bug when sending a specially crafted, chunked, encoded HTTP Message, resulting in a denial of service.
Отчет
As this flaw allows a remote attacker to cause a denial of service, it has been rated with an important severity. The Squid package as shipped in Red Hat Enterprise Linux 6 and 7 is not affected by this vulnerability because the vulnerable code was introduced in a newer version of Squid.
Меры по смягчению последствий
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
