openssl: OpenSSL: Denial of Service via unbounded QUIC connection identifier backlog

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by flooding a connection with connection identifier update requests while withholding acknowledgments. This behavior bypasses connection limits and forces the system to accumulate pending retirement frames, resulting...

openssl: openssl: Denial of Service via excessive QUIC packet buffer retention

A flaw was found in OpenSSL. A remote attacker can cause a Denial of Service DoS by sending specially crafted network packets to a QUIC protocol endpoint. Because the QUIC stack retains memory in packet buffers until the receiving application reads the stream data, an attacker can manipulate data...

DEBIAN-CVE-2026-103000

pypdf is a free and open-source pure-python PDF library. Prior to 6.19.0, a crafted PDF can provide unusually large alphabetical page-label values that cause pypdf/pagelabels.py to generate strings beyond a reasonable page-label length when an application retrieves document page labels, consuming...

CVE-2026-102995

pypdf is a free and open-source pure-python PDF library. Prior to 6.18.1, a crafted PDF can place unusually large source-code or destination-string tokens in a font /ToUnicode mapping, causing pypdf/cmap.py parsebfchar to decode and retain oversized values during operations such as text extractio...

DEBIAN-CVE-2026-102996

pypdf is a free and open-source pure-python PDF library. Prior to 6.18.1, a crafted PDF can provide a TrueType or Type1 simple font with an unusually large /Widths array, causing pypdf/font.py Font.collectttt1characterwidths to process entries beyond the 256 character codes meaningful for a simpl...

DEBIAN-CVE-2026-102993

pypdf is a free and open-source pure-python PDF library. Prior to 6.17.0, a crafted PDF can provide unusually large Roman page-label values that cause pypdf/pagelabels.py to generate excessively large numeral strings when an application retrieves document page labels, consuming large amounts of...

CVE-2026-102995

The pypdf pure-python PDF library is vulnerable to excessive memory consumption in versions prior to 6.18.1 . A crafted PDF can include unusually large source-code or destination-string tokens within a font /ToUnicode mapping. This causes the pypdf/_cmap.py parse_bfchar function to decode and ret...

CVE-2026-85532 Apache WSS4J: Insufficient Validation of Derived-Key Parameters

Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum leng...

CVE-2026-76992

The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a...
