Affected: AlmaLinux:9: libtirpc, AlmaLinux:9: libtirpc-devel

The libtirpc packages contain SunLib's implementation of transport-independent remote procedure call (TI-RPC) documentation, which includes a library required by programs in the nfs-utils and rpcbind packages.

In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections.

This can, in turn, lead to an svc_run infinite loop without accepting new connections. Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. A use-after-free in Busybox 1.35-x's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the copyvar function. A malicious server can serve excessive amounts of "Set-Cookie:" headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match a…

Security update for libtirpc

Affected: Ubuntu:16.04:LTS: ntirpc, Ubuntu:20.04:LTS: libtirpc, Ubuntu:22.04:LTS: libtirpc

In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections.

A new LTS Firmware release fixes known vulnerabilities in used open-source libraries. In addition, the following improvements have been implemented: HMI - Hardening against DoS attacks. - Hardening against memory leak problems in case of network attacks. WBM - Umlauts in the password of the 'User Manager' were not handled correctly. The password rule for upper and lower case was not followed. This could lead to unintentionally weaker passwords.- Hardening of WBM against Cross-Site-Scripting. User Manager - In security notifications 'SecurityToken' was always displayed as '0000000' when creating or modifying users.- Hardening of Trust and Identity Stores.

Ein lokaler Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um einen Denial of Service Angriff durchzuführen, Sicherheitsvorkehrungen zu umgehen oder sonstige Auswirkungen zu verursachen.
