https://notcve.org/view.php?id=CVE-2025-49176
17 Jun 2025 — A flaw was found in the Big Requests extension. The request length is multiplied by 4 before checking against the maximum allowed size, potentially causing an integer overflow and bypassing the size check. • https://access.redhat.com/security/cve/CVE-2025-49176 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2025-49175
17 Jun 2025 — A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash. USN-7573-1 fixed several vulnerabilities in X.Org. This update provides the corresponding update for Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. Nils Emmerich discovered that the X.Org X Server incorrectly handled certain memory operations. • https://access.redhat.com/security/cve/CVE-2025-49175 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2025-6199
17 Jun 2025 — A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image. • https://access.redhat.com/security/cve/CVE-2025-6199 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2025-6196
17 Jun 2025 — A flaw was found in libgepub, a library used to read EPUB files. The software mishandles file size calculations when opening specially crafted EPUB files, leading to incorrect memory allocations. This issue causes the application to crash. Known affected usage includes desktop services like Tumbler, which may process malicious files automatically when browsing directories. While no direct remote attack vectors are confirmed, any application using libgepub to parse user-supplied EPUB content could be vulnera... • https://access.redhat.com/security/cve/CVE-2025-6196 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2025-6020
17 Jun 2025 — A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions. Olivier BAL-PETRE discovered that the PAM pam_namespace module incorrectly handled user-controlled paths. In environments where pam_namespace is used, a local attacker could possibly use this issue to escalate their privileges to root. • https://access.redhat.com/security/cve/CVE-2025-6020 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

17 Jun 2025 — A privilege escalation from host to domain vulnerability was found in the FreeIPA project. The FreeIPA package fails to validate the uniqueness of the `krbCanonicalName` for the admin account by default, allowing users to create services with the same canonical name as the REALM admin. When a successful attack happens, the user can retrieve a Kerberos ticket in the name of this service, containing the admin@REALM credential. This flaw allows an attacker to perform administrative tasks over the REALM, leadin... • https://access.redhat.com/errata/RHSA-2025:9184 • CWE-1220: Insufficient Granularity of Access Control •

https://notcve.org/view.php?id=CVE-2025-49794
16 Jun 2025 — A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors. • https://access.redhat.com/security/cve/CVE-2025-49794 • CWE-825: Expired Pointer Dereference •

https://notcve.org/view.php?id=CVE-2025-6170
16 Jun 2025 — A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections. • https://access.redhat.com/security/cve/CVE-2025-6170 • CWE-121: Stack-based Buffer Overflow •

16 Jun 2025 — A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory. • https://access.redhat.com/security/cve/CVE-2025-49796 • CWE-125: Out-of-bounds Read •
