CVE-2026-81723

NLTK versions before 3.10.3 are affected by a quadratic CPU exhaustion vulnerability in XMLCorpusView._read_xml_fragment() . The function rescans all accumulated XML fragments on every 1 KiB block read, causing CPU consumption to grow quadratically with input size. An attacker can supply malforme...

nltk PorterStemmer in versions = 3.10.2 fixed in 3.10.3 contains an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem. The isconsonant helper walks backward over the entire run of trailing 'y' characters on every call, and measure invokes it for each stem position, causin...

CVE-2026-81721

openssl_encrypt before 1.4.9 fails to validate KDF cost parameters (Argon2, scrypt, or balloon) in encrypted file metadata and keystore headers. An unauthenticated attacker over the network can craft a malicious encrypted file declaring arbitrarily large KDF parameters, triggering unbounded memor...

CVE-2026-81720

openssl_encrypt before 1.4.9 fails to validate the memory_cost parameter found in identity file protection blocks. Because the value is passed unboundedly into Argon2 key derivation, an attacker with write access to local identity stores can craft a malicious identity file with an excessive memor...

CVE-2026-81720 openssl_encrypt before 1.4.9 Denial of Service via Unbounded Argon2

opensslencrypt before 1.4.9 fails to validate the memorycost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive...

CVE-2026-81720 openssl_encrypt before 1.4.9 Denial of Service via Unbounded Argon2

CVE-2026-68515

A flaw was found in OpenEXR. A remote attacker could exploit this vulnerability by providing specially crafted EXR image files to the exrmultiview utility. When processing these files, the utility can write beyond its allocated memory on the heap, leading to a heap out-of-bounds write. This could...

CVE-2026-81699

openssl_encrypt versions before 1.4.9 fail to properly validate key derivation function (KDF) costs in crafted files. An attacker can supply a malicious file with excessive KDF parameters over the network with no privileges required , triggering unbounded memory and CPU exhaustion during pre-auth...
