CVE-2024-25111

CVSS v3.1

8.6

High

VectorAV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Squid versions 3.5.27 through 6.7
Description The issue is related to an uncontrolled recursion bug in the HTTP Chunked decoder, which can lead to a Denial of Service attack. A remote attacker can exploit this by sending a crafted, chunked, encoded HTTP Message. This problem is associated with a buffer overflow on the stack due to the uncontrolled recursion when processing HTTP messages.
Recommendations For Squid versions 3.5.27 through 6.7, update to version 6.8 or apply patches from Squid's patch archives to resolve the issue. At the moment, there is no workaround for this issue, so updating or patching is the only resolution.
