In OCaml-tar before 3.4.0, a crafted archive with ../ path segments in its name allows escaping the current working directory. This is not desired behavior, and tar1 rejects such extractions, but ocaml-tar decompresses it anyway. The impact is that it allows arbitrary file writes outside of the...
CVE-2026-45388
In OCaml-TLS before 2.1.0, the client implementation does insufficient checks of the certificate provided by the server, which allows impersonation with certificates that are not meant for server authentication because of KeyUsage and ExtendedKeyUsage...
CVE-2026-45389
In OCaml-TLS before 2.1.0, the server implementation does insufficient checks of the certificate provided by the client when doing client authentication, which allows impersonation with certificates that are not meant for client authentication because of KeyUsage and ExtendedKeyUsage...

CVE-2026-45389
Summary (OCaml-TLS CVE-2026-45389): OCaml-TLS versions before 2.1.0 fail to properly validate KeyUsage and ExtendedKeyUsage on client certificates during mutual TLS, allowing impersonation with certificates intended for server authentication. The issue arises in the server-side certificate valida...
CVE-2026-45388
CVE-2026-45388 affects OCaml-TLS before 2.1.0. The TLS 1.3 client path in handshake_client13.ml did not wire into validate_keyusage, allowing a certificate issued for non-server purposes (e.g., clientAuth, codeSigning, emailProtection) to impersonate a TLS server if the EKU/KeyUsage restrictions ...

In OCaml-tar before 3.4.0, a crafted archive with ../ path segments in its name allows escaping the current working directory. This is not desired behavior, and tar1 rejects such extractions, but ocaml-tar decompresses it anyway. The impact is that it allows arbitrary file writes outside of the...
CVE-2026-45390
CVE-2026-45390 affects OCaml-tar before 3.4.0. A crafted archive containing "../" segments in file names can escape the extraction directory, allowing arbitrary file writes outside the target path when decompression is reachable. The OSV/ENISA reports show the vulnerable function uses Filename.co...

OSEC-2026-08 Path traversal vulnerability in ocaml-tar
A malicious archive with ../ path segments in its name allows escaping the current working directory. This is not desired behavior, and tar1 rejects such extractions, but ocaml-tar decompresses it anyway. The impact is that it allows arbitrary file write outside of the desired extraction director...

OSEC-2026-06 TLS-client (with TLS 1.3) does insufficient certificate checks (missing KeyUsage and ExtendedKeyUsage validation)
The ocaml-TLS 1.3 client does not validate the KeyUsage and ExtendedKeyUsage extensions of the server certificate. This can lead to impersonation with a certificate issued to a client. Scenario Every employee at a major bank carries a smart card. The card holds a clientAuth certificate issued by...

USN-8256-1 opam vulnerability
Andrew Nesbitt discovered that opam did not properly validate file destination paths in package install files. An attacker could use this issue to bypass sandbox protections and write files to arbitrary locations, possibly leading to arbitrary code execution...
MGASA-2026-0116 Updated opam packages fix security vulnerability

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 9b5d6fbb-4893-11f1-82bf-3c7c3fba4204 advisory. https://github.com/ocaml/opam/releases/tag/2.5.1 reports: In OCaml opam before 2.5.1, a .install field...
oxenstored keeps quota related use counts across domain destruction
ISSUE DESCRIPTION When oxenstored is tearing a domain down, the node data is cleaned up but the usage counts are leaked. When the domain ID is eventually reused, the new domain can create fewer nodes before beeing deemed to be over quota. IMPACT Over an extended period of time, new domains will b...
