DEBIAN-CVE-2026-80255

A Set-Cookie: header using tab horizontal tab, ASCII code 9 instead of space ascii code 32 immediately before the Secure attribute causes curl to store the cookie without its Secure flag. The cookie might then wrongfully be sent over plaintext HTTP on subsequent requests to the same host...

DEBIAN-CVE-2026-80229

When performing transfers via libcurl’s multi interface, pooled TLS connections can outlive their originating easy handles. In OpenSSL 3 provider configurations, libcurl attaches an allocated library context to the easy handle's state and passes it to OpenSSL without acquiring an ownership...

DEBIAN-CVE-2026-19931

A flaw in libcurl makes it wrongly reuse an HTTP connection setup for a given hostname using Negotiate authentication, when the initial request is done using empty credentials. This can make user B's request get sent over user A's previously authenticated connection...

DEBIAN-CVE-2026-18924

A flaw in libcurl's handling of HTTP/2 Server Push streams, when the parent handle is set to share connections with other handles, can lead to use-after-free in the cleanup process...

DEBIAN-CVE-2026-13608

A flaw in the libcurl SASL negotiation for LDAP authentication allows an incomplete handshake sequence to be misinterpreted as a successful cryptographic verification. An attacker executing a Man-in-the-Middle MITM attack can inject a premature or shortcut response that bypasses complete peer...

DEBIAN-CVE-2026-6554

libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely...

DEBIAN-CVE-2026-18313

rpcapd can allocate up to 65536 bytes per each RPCAPMSGUPDATEFILTERREQ or RPCAPMSGSTARTCAPREQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially faster...

DEBIAN-CVE-2026-31912

libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the...

DEBIAN-CVE-2026-0799

In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to tr...

DEBIAN-CVE-2026-6244

libpcap BPF interpreter for the 'div k' and 'mod k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero...

DEBIAN-CVE-2026-31911

libpcap BPF interpreter calls abort if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process...

DEBIAN-CVE-2026-18238

The rpcap client code that processes a RPCAPMSGPACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if it was a part of the...

DEBIAN-CVE-2026-86145

PCRE2 before 10.48 allows a pcre2dfamatch out-of-bounds write because reuse of a cached workspace block, in a recursive DFA matching workspace, lacks a size check even though a newly allocated block, for the same purpose, does have a size check. This outcome requires an attacker-controlled regula...

DEBIAN-CVE-2026-86143

In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a...
