Security researchers disclosed software flaws affecting Windows, macOS, Photoshop and Foxit Reader. Cisco Talos published the details October 7 and says the vendors had patched the reported issues.
Several bugs could let a specially prepared file or sequence of software calls expose information, corrupt memory or run code. One Windows flaw involved the NETIO.sys network driver. Others affected the Cloud Files Mini Filter Driver. Talos also described a macOS CoreWLAN information disclosure bug and two Foxit Reader flaws involving JavaScript inside PDF files.
A separate Photoshop installer flaw could allow a local attacker to gain higher privileges by replacing files with a malformed one. “Privilege escalation” means gaining more control on a device than an account should have. Talos lists the affected versions and tracking identifiers in its advisory roundup.
The post does not say attackers exploited these flaws in real attacks. Talos says they were disclosed under Cisco’s coordinated disclosure process after vendors issued fixes. That distinction matters: a vulnerability report describes what software could allow, not proof that someone used it.
The advisories cover several products, so there is no single patch to install. Users and administrators need to apply updates from each software vendor. Talos also published detection rules for its Snort network security system.
