CVE-2026-102505
Description détaillée
Imager versions before 1.037 for Perl overflow a heap buffer fetching float samples from a paletted image in i_gsampf_fp. For a paletted image, getsamples() with type "float" allocates a buffer of one sample per pixel and fetches every requested channel of each pixel into it. Requesting more than one channel writes past its end. An attacker-supplied image controls the overflowing bytes through its palette.

CVE-2026-9864
Fortra BoKS Server Agent contains a predictable password generation vulnerability in the adjoin utility. Machine-account passwords generated during Active Directory join or password renewal operations may have significantly less entropy than intended, making them more susceptible to prediction by an attacker who can estimate when the password was generated.
CVE-2026-94620
Classroom 50 is a free and open-source tool for managing and grading programming assignments via GitHub. Prior to version 1.11.0, `gh teacher download` clones each student's assignment repository and then writes autograde artifacts (`result.json` and `results.json`) into the just-cloned working tree. The write followed symlinks, so a student who committed `result.json` or `results.json` as a **symlink** (materialized verbatim by `git clone`) could redirect the teacher's write to an arbitrary path — e.g. `~/.zshrc`, `~/.ssh/authorized_keys`, a cron file, or an in-clone `.git/hooks/*` file that git subsequently executes. The written bytes are attacker-controlled (the student's uploaded release asset for `result.json`; student-chosen submit-tag names for `results.json`). This is an arbitrary file write leading to code execution as the teacher, whose `gh` token carries `admin:org`, `repo`, and `workflow` across the entire classroom organization. Version 1.11.0 contains a patch. Some workarounds are available. Avoid running `gh teacher download` against untrusted student repositories, or run it inside a disposable sandbox / container with no access to sensitive host files or credentials. Inspect cloned trees for symlinked, hardlinked, or special (`result.json`/`results.json`) entries before allowing the artifact-refresh step to run.
CVE-2026-79896
Fortra BoKS Manager contains an out-of-bounds read vulnerability in the custom TLS ClientHello parser used by boks_portmux. A remote unauthenticated attacker can submit a malformed ClientHello and terminate boks_portmux. Although the daemon is normally restarted automatically, repeated requests can sustain the service interruption.
