net/mail: golang: net/mail: Denial of Service via pathological email address parsing

A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...

CVE-2026-77680 Libsoup3: libsoup: quadratic cpu denial of service in http range coalescing after cve-2025-32907 fix

An algorithmic complexity flaw exists in libsoup's HTTP Range header processing that persists after the CVE-2025-32907 fix. CVE-2025-32907 addressed memory amplification when a client repeated the same range many times in a single Range header. Commit 9bb92f7a corrected merge correctness in...

CVE-2026-77680

libsoup contains an algorithmic complexity flaw in its HTTP Range header processing that persists after the CVE-2025-32907 fix. The root cause is that the coalescing loop in soup_message_headers_get_ranges_internal() uses g_array_remove_index() for each merged range, resulting in O(N²) work when ...

CVE-2026-55620

emlparser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information. Prior to 3.0.2, emlparser.routing.noparenthesis in emlparser/routing.py removes parenthesized CFWS comments from Received: headers with a regex-based...

eml_parser vulnerable to DoS via deeply nested parens in Received headers

Summary emlparser strips parenthesised CFWS comments from Received: headers using a regex-based fix-point loop. The loop has quadratic time complexity in the number of nested parens. A single Received: header containing 5,000 nested parens causes 1.3 seconds of CPU saturation per parsed message;...

CVE-2026-79658 Ech0 before 5.0.1 Denial of Service via Accept-Language

Ech0 before 5.0.1 does not impose any size or shape limit on the Accept-Language header processed by its i18n middleware, which runs on every HTTP request. The header is passed unfiltered to go-i18n's NewLocalizer, which internally calls golang.org/x/text/language.ParseAcceptLanguage. The...

CVE-2026-79658

Ech0 versions before 5.0.1 are vulnerable to a denial-of-service attack via the Accept-Language header. The i18n middleware, which runs on every HTTP request, passes the header unfiltered to golang.org/x/text/language.ParseAcceptLanguage. A gap in the CVE-2022-32149 mitigation caps - characters b...

Astra Linux – Vulnerability found in Python 3.11, Python 2.7, and Python 3.7

There is a low-severity vulnerability affecting CPython, specifically the ‘http.cookies’ standard library module. When parsing cookies where quotes were represented by backslashes in the cookie value, the parser uses an algorithm with quadratic complexity, resulting in excessive CPU resources bei...

Astra Linux – Vulnerability in pillow

A issue was discovered in Pillow prior to version 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to handle any combination of \r and \n as line endings. This implementation uses a quadratic method of accumulating lines while searching for a line ending. A malicious EPS...

Astra Linux – Vulnerability in pypdf2

pypdf is a pure-Python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. An attacker who exploits this vulnerability can create a PDF that results in unexpected long execution times. This quadratic execution time blocks the current process and can even...

Astra Linux - Vulnerability in Golang-1.19

Within HostnameError.Error, when constructing an error string, there is no limit to the number of hosts that will be printed out. Moreover, the error string is created through repeated string concatenation, resulting in quadratic runtime. Therefore, a certificate provided by a malicious actor can...
