EulerOS 2.0 SP8 : libproxy (EulerOS-SA-2020-2304)

critical Nessus Plugin ID 142180


The remote EulerOS host is missing multiple security updates.


According to the versions of the libproxy packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header.(CVE-2020-26154)

- url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.(CVE-2020-25219)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libproxy packages.
