CVE-2007-1804
HighSummary
PulseAudio w wersji 0.9.5 pozwala zdalnym atakującym na spowodowanie awarii demona (denial of service) poprzez wysłanie określonych wartości na porcie TCP 9875 lub pustego pakietu na porcie UDP 9875. Wykorzystanie tych luk prowadzi do różnych błędów asercji w kodzie.
Risk Assessment
Organizacja może doświadczyć przerw w działaniu usług audio, co może wpłynąć na dostępność systemów korzystających z PulseAudio. Zdalni atakujący mogą wykorzystać te luki do destabilizacji systemu.
Recommendation
Zaleca się aktualizację PulseAudio do najnowszej wersji, aby usunąć znane luki. Dodatkowo, warto ograniczyć dostęp do portów 9875 tylko do zaufanych użytkowników i źródeł.

The @sap/cds-mtxs NPM library does not perform sufficient checks on certain functionality used in multitenant CAP applications with extensibility enabled. An unauthenticated attacker could send specially crafted requests to obtain sensitive credentials and abuse them to replace or delete tenant data. Successful exploitation can result in a high impact on availability and integrity of the application, and partial impact on confidentiality of business data.
- CVE-2026-66768Critical
SAP GUI for Java does not correctly enforce the trust level policy for certain functions invoked from a connected backend system. A low-privileged attacker could exploit this weakness by manipulating a connected backend system to trigger affected functionality. This could allow arbitrary command execution on the victim's machine, leading to a high impact on confidentiality, integrity, and availability.

In JetBrains Hub before 2026.2.52442, an unauthenticated attacker could register a trusted service and gain superuser privileges.
Original NVD description (English source)
PulseAudio 0.9.5 allows remote attackers to cause a denial of service (daemon crash) via (1) a PA_PSTREAM_DESCRIPTOR_LENGTH value of FRAME_SIZE_MAX_ALLOW sent on TCP port 9875, which triggers a p->export assertion failure in do_read; (2) a PA_PSTREAM_DESCRIPTOR_LENGTH value of 0 sent on TCP port 9875, which triggers a length assertion failure in pa_memblock_new; or (3) an empty packet on UDP port 9875, which triggers a t assertion failure in pa_sdp_parse; and allows remote authenticated users to cause a denial of service (daemon crash) via a crafted packet on TCP port 9875 that (4) triggers a maxlength assertion failure in pa_memblockq_new, (5) triggers a size assertion failure in pa_xmalloc, or (6) plays a certain sound file.
