This update for cifs-utils fixes the following issue: - CVE-2026-104715: mount options injection via CIFS credentials-file parsing (bsc#1284932).
This update for mutt fixes the following issue: - CVE-2026-107570: heap out-of-bounds write in `convert_file_from_to()` via a crafted `Content-Type` header (bsc#1284739).
This update for cyrus-sasl fixes the following issue: - CVE-2026-107161: Heap buffer overflow in cyrus-sasl add_to_challenge() allows malicious server to crash or compromise DIGEST-MD5 clients (bsc#1284687).
This update for libpng16 fixes the following issues: - CVE-2026-46675: Use-after-free of zlib input in `png_read_end` after incomplete zTXt, iTXt or iCCP decompression (bsc#1283183). Changes for libpng16: - version update to 1.6.59 (jsc#PED-16190): * Fixed a regression introduced in version 1.6.47 that caused libpng to reject hIST chunks in their correct position, after PLTE. * Prevented a double free of `png_struct` members after an allocation failure. * Applied fixes and updates to the CMake build. * Adopted the REUSE Specification for licensing the CI files.
A malicious SVG can trigger an integer overflow which in turn triggers a null-pointer dereference in VectorImage QML Type.
NLnet Labs Unbound, 1.22.0 up to and including version 1.26.1, contains a DNS-over-QUIC (DoQ) lifetime bug reachable by a remote DoQ client under multi-threaded operation. A client-triggered QUIC path migration can enter stream/connection cleanup while a mesh reply still retains a pointer to the DoQ stream. Cleanup frees the DoQ stream and when the pending mesh reply later completes it dereferences a stale pointer leading to a crash.
NLnet Labs Unbound up to and including version 1.26.1 limits compression-pointer traversal for each individual domain-name operation but has no aggregate inbound decompression-work budget. Many chained compression pointers in a message results in a lot of CPU usage following them. A malicious actor with recursive-query access and control of an ordinarily delegated authority that serves specially crafted replies can exploit the vulnerability and degrade Unbound's general performance.
When NLnet Labs Unbound up to and including version 1.26.1 is configured with both a root trust anchor and an additional 'trust-anchor:' for an island-of-security zone whose parent is provably insecure under the root chain, a malicious actor who can deliver one forged NXDOMAIN response for a name inside the island, with the NSEC/SOA RRSIG 'SignerName' set to the insecure parent, tricks Unbound's validator to use the root trust anchor instead, and consecutively the insecure parent, thus causing that record to be treated as insecure and denying existence for records in the trust island.
When NLnet Labs Unbound 1.0.1 up to and including version 1.26.1 is configured with both a root trust anchor and an additional 'trust-anchor:' for an island-of-security zone whose parent is provably insecure under the root chain, a malicious actor with a forged NSEC reply with the SOA bit cleared can trick Unbound to treat the configured trust island as insecure. This happens because the DNSSEC validator in Unbound accepts and caches the NSEC insecure response bypassing the RRSIG validation that the validator was supposed to do. The acceptance of the NSEC record at the trust anchor apex was allowed due to and old fix for type DS and NSEC quer
This update for libsoup fixes the following issues: - CVE-2026-12547: Header "Proxy-Authorization" leads to credentials being send to different proxy after proxy switch (bsc#1272195). - CVE-2026-12548: out-of-bounds read in multipart body parser due to an integer truncation (bsc#1272196). - CVE-2026-15711: SoupWebsocketConnection: WebSocket remote denial of service via oversized control frame protocol violation (bsc#1271446). - CVE-2026-15712: SoupClientMessageIOHTTP2: HTTP/2 GOAWAY frame parsing heap buffer over-read via invalid NUL- termination assumption (bsc#1271447). - CVE-2026-15713: SoupCache: libsoup: HTTP/2 frame window exhaus
In NLnet Labs Unbound up to and including version 1.26.1, an observable cache-level side-channel can be exposed with 'unwanted-reply-threshold > 0' configurations (not a default configuration). If a response-like UDP datagram reaches the upstream source port currently used by a recursive query, but its TXID does not match any pending query, Unbound counts the packet as an unwanted reply. When the accumulated count reaches the configured threshold, Unbound clears the worker's RRset cache and message cache. This cache clear action does not destroy the current upstream UDP pending query. Therefore, an external observer can distinguish whether a
This update for openssh fixes the following issues: - CVE-2026-73282: unsynchronized remote forwarding updates in SSH client multiplexing can cause use-after-free (bsc#1275074). - CVE-2026-73283: unenforced restriction keywords on tunnel forwarding can allow administrative security policy bypasses (bsc#1275079).
This update for coreutils fixes the following issue: - CVE-2026-56391: uniq: denial of service and information disclosure via out-of-bounds read with multibyte input (bsc#1272698).
