DLA 1266-1: squid3 security update

Package : squid3
Version : 3.1.20-2.2+deb7u8
CVE ID : CVE-2018-1000024 CVE-2018-1000027
Debian Bug : 888719 888720


Squid, a high-performance proxy caching server for web clients, has been
found vulnerable to denial of service attacks associated with ESI
response processing and intermediate CA certificate downloading.

CVE-2018-1000024

Incorrect pointer handling resulted in the ability of a remote
server to return a crafted ESI response which could trigger a denial
of service for all clients accessing the Squid service. This issue
affects the Squid custom ESI parser.

CVE-2018-1000027

Incorrect pointer handling resulted in the possibility of a remote
client delivering certain HTTP requests in conjunction with certain
trusted server reponses involving the processing of ESI responses or
downloading of intermediate CA certificates to trigger a denial of
service for all clients accessing the squid service.

For Debian 7 "Wheezy", these problems have been fixed in version
3.1.20-2.2+deb7u8.

We recommend that you upgrade your squid3 packages.

Version : 9.20.1~dfsg.1-4+deb7u3

The p7zip package has a heap-based buffer overflow in the
NCompress::NShrink::CDecoder::CodeReal method in 7-Zip which allows
remote attackers to cause a denial of service (out-of-bounds write) or
potentially execute arbitrary code via a crafted ZIP archive.

For Debian 7 "Wheezy", these problems have been fixed in version
9.20.1~dfsg.1-4+deb7u3.

We recommend that you upgrade your p7zip packages.
