Friday Squid Blogging: COVID-19 Found on Chinese Squid Packaging

I thought the virus doesnt survive well on food packaging: Authorities in China’s northeastern Jilin province have found the novel coronavirus on the packaging of imported squid, health authorities in the city of Fuyu said on Sunday, urging anyone who may have bought it to get themselves tested. ...

[SECURITY] Fedora 33 Update: squid-4.13-1.fc33

Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DN...

Authorization Bypass

squid is vulnerable to authorization bypass. When handling a URN request, the corresponding HTTP request that is made does not go through the access checks, allowing an attacker to bypass access checks and gain access to restricted HTTP servers such as HTTP servers listening on localhost...

Buffer Overflow

squid:eoan is vulnerable to buffer overflow. An issue was discovered in Squid when Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has ...

Denial Of Service (DoS)

Squid is vulnerable denial of service DoS. It allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cachepeer is used with the cache digests feature. The problem exists because...

Denial Of Service (DoS)

squid is vulnerable to denial of service DoS. The vulnerability exists due to an incorrect input validation, causing a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy...

HTTP Request Smuggling

squid3 is vulnerable to HTTP request smuggling. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches between a client and Squid with attacker-controlled content ...

Arbitrary Code Execution

squid is vulnerable to arbitrary code execution. The vulnerability exists as a heap-based buffer overflow could occur when receiving data from a remote server in response to an URN request, and when squid fails to ensure that the response can fit within the buffer...

HTTP Request Smuggling

Squid is vulnerable to HTTP request smuggling. An attacker is able to smuggle HTTP requests due to insecure data validation in the Content-Length header. This vulnerability allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches...
