sha256crypt and sha512crypt through 0.6 allow attackers to cause a denial of service (CPU consumption) because the algorithm's runtime is proportional to the square of the length of the password.

The C++ symbol demangler routine in cplus-dem.c in libiberty, as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted file, as demonstrated by a call from the Binary File Descriptor (BFD) library (aka libbfd).

A vulnerability classified as problematic has been found in GNU Binutils 2.43. Affected is the function xstrdup of the file xstrdup.c of the component ld. The manipulation leads to memory leak. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."

When asked to use a .netrc file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances.

This flaw only manifests itself if the netrc file has a default entry that omits both login and password. A rare circumstance.

curl's websocket code did not update the 32 bit mask pattern for each new outgoing frame as the specification says. Instead it used a fixed mask that persisted and was used throughout the entire connection.

A predictable mask pattern allows for a malicious server to induce traffic between the two communicating parties that could be interpreted by an involved proxy (configured or transparent) as genuine, real, HTTP traffic with content and thereby poison its cache. That cached poisoned content could then be served to all users of that proxy.

When doing TLS related transfers with reused easy or multi handles and altering the CURLSSLOPT_NO_PARTIALCHAIN option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.

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.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.

NVD Description

Note: Versions mentioned in the description apply only to the upstream shadow package and not the shadow package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

shadow-utils (aka shadow) 4.4 through 4.17.0 establishes a default /etc/subuid behavior (e.g., uid 100000 through 165535 for the first user account) that can realistically conflict with the uids of users defined on locally administered networks, potentially leading to account takeover, e.g., by leveraging newuidmap for access to an NFS home directory (or same-host resources in the case of remote logins by these local network users). NOTE: it may also be argued that system administrators should not have assigned uids, within local networks, that are within the range that can occur in /etc/subuid.

Remediation

There is no fixed version for Ubuntu:24.04 shadow.
