USN-8736-2: Perl vulnerabilities

Ubuntu issued USN-8736-2 fixing two Perl regex flaws that could cause out-of-bounds heap access, denial of service, or security bypass on 24.04 LTS.

USN-8736-2 backports the Perl fixes from USN-8736-1 to Ubuntu 24.04 LTS. CVE-2026-15534 involves out-of-bounds heap reads or writes when regular expressions handle large inputs, potentially causing denial of service or arbitrary code execution. CVE-2026-19487 causes incorrect regex matching with alternative branches, allowing security restrictions to be bypassed.

The GNU C Library security advisories update for 2026-09-14

glibc advisory GLIBC-SA-2026-0017 discloses a buffer overflow in strfmon/strfmon_l affecting versions 2.38 through 2.44.

The GNU C Library published security advisories including GLIBC-SA-2026-0017, a buffer overflow in strfmon and strfmon_l. Calling these functions with right-justified width padding conversions can write past the end of the caller-supplied output buffer in glibc 2.38 to 2.44. Exploitation requires an application code path that calls strfmon with attacker-influenced parameters.

Re: Retrospective by 'gpg.fail' authors

oss-security follow-up to a gpg.fail authors' retrospective argues that GnuPG's unmaintained, forgotten code is a security liability and should be deleted.

On the oss-security mailing list, Soatok Dreamseeker responds to a retrospective published by the gpg.fail authors, asking why unmaintained code is retained and stating that forgotten, unmaintained code is a liability and effectively unmaintained by definition. The visible reply addresses Werner Koch and concerns GnuPG code maintenance. No specific CVE, flaw, or exploitation is described in this snippet.

Forgery of C2PA on a Pixel 10

Researcher forged a Google Pixel 10 C2PA content credential with genuine signatures, showing root-level attackers can fake photo provenance.

A Hacker Factor blog post demonstrates an AI-generated 'unicorn glitter milk' news photo carrying a valid, cryptographically signed C2PA manifest traceable to Google's Pixel camera certificate chain, passing validation in Adobe Inspect and the CAI Verify tool with a verified timestamp. The author, working with UMBC's PASAWG working group, reported to Google and C2PA in November 2025 that root access on a Pixel device could sign arbitrary images as camera captures; after 90 days without resolution, details were published. The finding undermines C2PA Assurance Level 2 claims made for Pixel 10 Content Credentials.

CVE-2026-86304: MojoX::Authentication versions before 0.006 for Perl allow SAML authentication bypass because parse_assertion builds Net::SAML2::Binding::POST without a trust anchor

MojoX::Authentication before 0.006 for Perl allows SAML authentication bypass because parse_assertion builds Net::SAML2::Binding::POST without a trust anchor (CVE-2026-86304).

CVE-2026-86304 affects MojoX::Authentication versions before 0.006 for Perl. The parse_assertion function builds Net::SAML2::Binding::POST without a trust anchor, so SAML assertions are not validated against a trusted signing key, enabling authentication bypass. The flaw is fixed in version 0.006 of the module.

Scans Targeting Hospitality Applications, (Wed, Sep 16th)

Scans from a bulletproof-hosting IP target the abandoned PIAF-HMS hospitality application, which contains numerous unpatched SQL injection flaws.

SANS ISC observed requests for /PIAF-HMS/ using the unusual user-agent Farez-Sorter/1.0, along with paths like /admin/, /ucp/, /hms/, and /hotel/, starting September 15 from the single source IP 94.102.49.125 (IP Volume, AS202425, a bulletproof hoster). PIAF-HMS, a PBX in a Flash Hospitality Management System, was last updated 10 years ago and a SQL injection vulnerability was reported recently; the code shows many injection flaws and lacks authentication and access control. The handler notes hotels are soft targets for personal data theft and guest MitM attacks, and asks for community insight on the campaign.

Critical ArangoDB Flaws Allow Authentication Bypass and Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8 and 9.9) enable unauthenticated API access and root code execution; fixes shipped in version 3.12.11

Remedio researchers found two ArangoDB flaws: GHSA-rrgq-978q-36mq (CVSS 9.8), an authentication bypass caused by the server inconsistently interpreting URL-encoded '/_api' paths, and GHSA-rvhw-4hpw-9vrx (CVSS 9.9), which lets users with database write access run JavaScript tasks with root privileges via the isSystem flag. Chained, they allow administrative database access without credentials, theft of the root password hash, and root code execution, exposing files such as /etc/shadow, TLS keys and cluster signing material on the official container image. ArangoDB shipped fixes in version 3.12.11 on August 31, 2026, with advisories published September 6; CVE identifiers were still pending. Users on 3.12.10.1 or earlier should upgrade, restrict exposure and rotate potentially exposed credentials.

Shasta County registrar of voters Clint Curtis said he plans to hire former Mesa County clerk Tina Peters as assistant registrar after Colorado Governor Jared Polis commuted her nine-year sentence for seven felonies, including identity theft, breaking into an election office, and stealing voting system software. Senators Alex Padilla and Adam Schiff asked California Secretary of State Shirley Weber to provide maximum oversight to prevent Peters from improperly accessing ballots, voting systems, or data of over 100,000 registered voters. The county board of supervisors recently censured Curtis after investigations found he was verbally abusive or physically threatening toward staff.

They found only 1 of 3 characterized DNS injectors matched Geedge code, noted the system relies on memory-unsafe C components and copied third-party code, and said its bugs could aid future circumvention tools. Geedge also exports censorship tools to Kazakhstan, Ethiopia, Pakistan, and Myanmar. The newsletter additionally rounds up multiple breaches.
