A use-after-free flaw was found in the way samba AD DC LDAP servers, handled 'Paged Results' control is combined with the 'ASQ' control. A malicious user in a samba AD could use this flaw to cause denial of service. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2. Se encontró un fallo de uso de la memoria previamente liberada en el modo en que los servidores samba AD DC LDAP, manejaron el control de "Paged Results" que es combinado con el control "ASQ".

In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur. En el kernel de Linux versión 4.9 hasta la versión 5.6.7, en la plataforma s390, una ejecución de código puede presentarse debido a una condición de carrera, como es demostrado por el código en la función enable_sacf_uaccess en el archivo arch/s390/lib/uaccess.c que presenta un fallo al proteger contra una actualización concurrente de la tabla de página, también se conoce como CID-3f777e19d171.

An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id. Normally such packets are dropped, but if this packet arrives before the data channel crypto parameters have been initialized, the victim's connection will be dropped. This requires careful timing due to the small time window (usually within a few seconds) between the victim client connection starting and the server PUSH_REPLY response back to the client. This attack will only work if Negotiable Cipher Parameters (NCP) is in use. • https://bugzilla.suse.com/show_bug.cgi?id=1169925 https://community.openvpn.net/openvpn/ticket/1272 https://github.com/OpenVPN/openvpn/commit/37bc691e7d26ea4eb61a8a434ebd7a9ae76225ab https://lists.debian.org/debian-lts-announce/2022/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FGHHV4YZANZW45KZTJJGVGPFMSXYRCKZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JII7RYYYRBPQNEGGVSOXCM7JUZ43T3VH https://patchwork.openvpn.net/patch/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

HTCondor up to and including stable series 8.8.6 and development series 8.9.4 has Incorrect Access Control. It is possible to use a different authentication method to submit a job than the administrator has specified. If the administrator has configured the READ or WRITE methods to include CLAIMTOBE, then it is possible to impersonate another user to the condor_schedd. (For example to submit or remove jobs) HTCondor versiones hasta e incluyendo una serie estable 8.8.6 y la serie de desarrollo 8.9.4, tiene un Control de Acceso Incorrecto.

An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials). Se detectó un problema en Squid versiones anteriores a 5.0.2. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html http://master.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch http://www.openwall.com/lists/oss-security/2020/04/23/2 http://www.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch https://bugzilla.suse.com/show_bug.cgi?id=1170313 https://github.com/squid-cache/squid/commit/eeebf0f37a72a2de08348e85ae34b02c34e9a811 https://github.com/squid-cache/squid/pull/585 • CWE-190: Integer Overflow or Wraparound CWE-284: Improper Access Control •
