CVE-2025-9230 (GCVE-0-2025-9230)

Vulnerability from cvelistv5 – Published: 2025-09-30 13:17 – Updated: 2025-11-04 21:15

Title

Out-of-bounds read & write in RFC 3211 KEK Unwrap

Summary

Issue summary: An application trying to decrypt CMS messages encrypted using password based encryption can trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which can have various consequences including a Denial of Service or Execution of attacker-supplied code. Although the consequences of a successful exploit of this vulnerability could be severe, the probability that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in CMS messages is very rarely used. For that reason the issue was assessed as Moderate severity according to our Security Policy. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary.

Severity ?

No CVSS data available.

CVE-2025-65018 (GCVE-0-2025-65018)

Vulnerability from cvelistv5 – Published: 2025-11-24 23:50 – Updated: 2025-11-25 19:29

Title

LIBPNG is vulnerable to a heap buffer overflow in `png_combine_row` triggered via `png_image_finish_read`

Summary

LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, there is a heap buffer overflow vulnerability in the libpng simplified API function png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. Attacker-crafted interlaced PNG files cause heap writes beyond allocated buffer bounds. This issue has been patched in version 1.6.51.

Severity ?

7.1 (High)

CVE-2025-9086 (GCVE-0-2025-9086)

Vulnerability from cvelistv5 – Published: 2025-09-12 05:10 – Updated: 2026-01-08 09:51

Title

Out of bounds read for cookie path

Summary

1. A cookie is set using the `secure` keyword for `https://target` 2. curl is redirected to or otherwise made to speak with `http://target` (same hostname, but using clear text HTTP) using the same cookie set 3. The same cookie name is set - but with just a slash as path (`path=\"/\",`). Since this site is not secure, the cookie *should* just be ignored. 4. A bug in the path comparison logic makes curl read outside a heap buffer boundary The bug either causes a crash or it potentially makes the comparison come to the wrong conclusion and lets the clear-text site override the contents of the secure cookie, contrary to expectations and depending on the memory contents immediately following the single-byte allocation that holds the path. The presumed and correct behavior would be to plainly ignore the second set of the cookie since it was already set as secure on a secure host so overriding it on an insecure host should not be okay.

The same cookie name is set - but with just a slash as path (`path=\\\"/\\\",`).\n   Since this site is not secure, the cookie *should* just be ignored.\n4. A bug in the path comparison logic makes curl read outside a heap buffer\n   boundary\n\nThe bug either causes a crash or it potentially makes the comparison come to\nthe wrong conclusion and lets the clear-text site override the contents of the\nsecure cookie, contrary to expectations and depending on the memory contents\nimmediately following the single-byte allocation that holds the path.\n\nThe presumed and correct behavior would be to plainly ignore the second set of\nthe cookie since it was already set as secure on a secure host so overriding\nit on an insecure host should not be okay."
