exploit-CVE-2016-6515

OpenSSH remote DOS Before 7.3 OpenSSH does not limit password lengths for password authentication, which allows remote attackers to cause a denial of service crypt CPU consumption via a long string. This bug resides in auth-passwd.c in authpassword function. Attackers can exploit this issue to...

CVE-2026-84311

A flaw was found in pypdf, a pure-python PDF library. A remote attacker can exploit this vulnerability by crafting a malicious PDF document containing specially structured XForm objects. Processing this document can lead to excessive iteration, causing the application to consume significant memor...

CVE-2026-84305

sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, sqlparse.formatsql, reindent=True and sqlformat --reindent route attacker-controlled parenthesized tuple lists through ReindentFilter.getoffset in sqlparse/filters/reindent.py, where flattenuptotoken repeatedly rebuilds an...

CVE-2026-81725

A flaw was found in NLTK, specifically within the Pl196xCorpusReader component. A remote attacker can exploit this by supplying malformed Text Encoding Initiative TEI blocks containing numerous unmatched opening tags. This triggers a regular expression denial of service ReDoS vulnerability, causi...

EUVD-2026-68962

Uncontrolled Resource Consumption vulnerability in ash-project ash allows an attacker to force an expensive regular expression to run on input that a length constraint should have already rejected. Ash.Type.String.applyconstraints/2 lib/ash/type/string.ex evaluated the :match regex regardless of...

Uncontrolled Resource Consumption vulnerability in ash-project ash allows an attacker to force an expensive regular expression to run on input that a length constraint should have already rejected. Ash.Type.String.apply constraints/2 lib/ash/type/string.ex evaluated the :match regex regardless of...

USN-8706-1 zlib vulnerability

It was discovered that zlib incorrectly handled negative length parameters in CRC32 combine functions. An attacker could use this issue to cause a denial of service via excessive CPU consumption...

CVE-2026-33607

An attacker that has valid credentials can use IMAP LIST command to consume CPU. This can cause degradation or denial of service for IMAP. Monitor system for abnormal CPU usage and kill the offending process and lock account. Alternatively install fixed version. No publicly available exploits are...

CVE-2022-30780 - lighttpd Remote Denial of Service Beschreibung Lighttpd 1.4.56 bis 1.4.58 ermöglicht einem entfernten Angreifer, einen Denial of Service CPU-Auslastung durch hängende Verbindungen zu verursachen, weil connectionreadheadermore in connections.c einen Tippfehler enthält, der die...

CVE-2026-81725 NLTK before 3.10.3 Regular Expression Denial of Service via Pl196xCorpusReader

NLTK before 3.10.3 contains a regular expression denial of service vulnerability in Pl196xCorpusReader that allows attackers to cause quadratic CPU consumption by supplying malformed TEI blocks with many unmatched opening tags. Attackers can exploit lazy regex patterns in the readblock method...

CVE-2026-81725

NLTK before 3.10.3 contains a Regular Expression Denial of Service vulnerability in the Pl196xCorpusReader component. The root cause lies in lazy regex patterns within the read_block method, which can be triggered by supplying malformed TEI blocks containing many unmatched opening tags. Attackers...

CVE-2026-81725 NLTK before 3.10.3 Regular Expression Denial of Service via Pl196xCorpusReader

NLTK before 3.10.3 contains a regular expression denial of service vulnerability in Pl196xCorpusReader that allows attackers to cause quadratic CPU consumption by supplying malformed TEI blocks with many unmatched opening tags. Attackers can exploit lazy regex patterns in the readblock method...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

CVE-2026-59887

A flaw was found in linkify-it, a library for recognizing links. A remote attacker could exploit this vulnerability by providing specially crafted user text. The mailto: schema validator, when processing this input, can be repeatedly invoked, leading to excessive CPU consumption. This can result ...

CVE-2026-66046

Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts function in xmlparse.c, where processing N specified attributes with non-normalized values triggers an ON^2 linear scan of elementType-defaultAtts to determine CDATA status. ...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the groupcomments function in sqlparse/engine/grouping.py when parsing a statement composed entirely of comment tokens e.g., repeated -- c\n lines.
