libXfont2: BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow

A flaw was found in libXfont2. In the BitmapScaleBitmaps function, an integer overflow can occur when calculating the memory needed for font glyphs. This overflow leads to a heap buffer overflow, where a smaller-than-required memory buffer is allocated. A local attacker can exploit this by loadin...

UBUNTU-CVE-2026-18739

A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacke...

CVE-2026-67216

cJSON through 1.7.19 contains an inefficient algorithmic complexity flaw in cJSONCompare. When comparing objects, the function recurses into each shared subtree twice, once in each direction, with no depth guard, making the running time exponential in nesting depth. A small, deeply nested documen...

openjdk: Enhance AWT ImagingLib (Oracle CPU 2026-07)

A flaw was found in OpenJDK. When the software processes certain images, a specific function fails to manage memory boundaries correctly. This can lead to the application attempting to access invalid memory or dereference a null pointer, which may cause the application to unexpectedly terminate...

UBUNTU-CVE-2026-64611

A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially...

UBUNTU-CVE-2026-16560

A heap-buffer-overflow flaw was found in Directory Server 389-ds-base. When a DN contains a legacy-quoted value, the server won't close the heap allocation allowing another call to refer to the same memory pointer causing a denial of service or an arbitrary memory write operation...

UBUNTU-CVE-2026-44690

In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, insufficient validation of the RRSIG.Labels field combined with premature cache writes during RFC 8198 aggressive NSEC processing leads to cache poisoning that permits a malicious actor controlling a single delegated zone to poison arbitrary...

A malicious BuildKit client or frontend could craft a request that could lead to BuildKit daemon crashing with a panic...

CVE-2026-59851

A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users...

Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS : alsa-lib vulnerability (USN-8538-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8538-1 advisory. It was discovered that alsa-lib incorrectly handled certain ALSA configuration text. An attacker could use this issue to cause alsa-lib to...

CVE-2026-59935

A flaw was found in pypdf, a pure-python PDF library. A remote attacker can craft a malicious PDF file containing an unterminated inline image within the page content stream. When this crafted PDF is parsed, it can lead to an infinite loop, resulting in a denial of service DoS due to resource...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

ruby/net-imap: ruby: Net::IMAP: IMAP Command Injection via Symbol Arguments

A flaw was found in Net::IMAP, a Ruby library that provides Internet Message Access Protocol IMAP client functionality. This vulnerability allows a remote attacker to inject arbitrary IMAP commands. This is achieved by passing specially crafted symbol arguments to IMAP commands. Successful...

CVE-2026-13758

CVE-2026-13758 affects CryptX for Perl versions before 0.088_001. The vulnerability stems from a non-constant-time comparison of AEAD authentication tags in the streaming decrypt_done path, using memNE (memcmp() != 0). The run time varies with the number of matching leading bytes across all five ...

EUVD-2026-40151

A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT8BITABGR output format and a specific stride value, leading to a heap-base...

CVE-2025-15661

A flaw in libssh2's sftpsymlink function allows a malicious SSH server or man-in-the-middle attacker to trigger an out-of-bounds heap read via a crafted SSHFXPNAME response. This can disclose heap memory contents or crash the application, causing a denial of service DoS. Mitigation Implement stri...

DEBIAN-CVE-2026-53260

In the Linux kernel, the following vulnerability has been resolved: tcp: Add preemptdisable,enablenested in reqskqueuehashreq. syzbot reported a weird reqsk-rskrefcnt underflow in inetcskreqskqueuedrop. The captured reqskput in inetcskreqskqueuedrop is called only when it successfully removes req...

libcurl: libcurl: Certificate validation bypass due to incorrect connection reuse

A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority CA trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA...
