Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2020-21819
HighEPSS 62%

A heap-based buffer overflow vulnerability was discovered in GNU LibreDWG version 0.10.2641 in the htmlescape function within escape.c. This flaw could allow an attacker to execute arbitrary code or cause a system crash.

CVE-2020-21818
HighEPSS 62%

A heap-based buffer overflow vulnerability was found in GNU LibreDWG version 0.10.2641 in the htmlescape function within escape.c at line 48. This flaw allows uncontrolled memory writes beyond the allocated buffer.

CVE-2020-21816
HighEPSS 62%

A heap-based buffer overflow vulnerability exists in GNU LibreDWG version 0.10.2641 in the htmlescape function at ../../programs/escape.c:46. This flaw allows for uncontrolled memory writes.

CVE-2020-21814
HighEPSS 61%

A heap-based buffer overflow vulnerability was discovered in GNU LibreDWG version 0.10.2641 in the htmlwescape function at escape.c line 97. This issue can lead to unexpected program behavior.

CVE-2020-21813
HighEPSS 51%

A heap-based buffer overflow vulnerability was discovered in GNU LibreDWG version 0.10.2641 in the output_TEXT function at programs/dwg2SVG.c:114. This flaw could allow an attacker to execute arbitrary code or cause a denial of service.

CVE-2021-3483
High

A flaw was found in the Nosy driver in the Linux kernel. This issue allows a device to be inserted twice into a doubly-linked list, leading to a use-after-free when one of these devices is removed. The highest threat is to confidentiality, integrity, and system availability. Versions before kernel 5.12-rc6 are affected.

CVE-2021-29053
HighEPSS 63%

Multiple SQL injection vulnerabilities in Liferay Portal 7.3.5 and Liferay DXP 7.3 before fix pack 1 allow remote authenticated users to execute arbitrary SQL commands via the classPKField parameter in CommerceChannelRelFinder.countByC_C and CommerceChannelRelFinder.findByC_C.

CVE-2021-29047
HighEPSS 60%

The SimpleCaptcha implementation in Liferay Portal 7.3.4, 7.3.5 and Liferay DXP 7.3 before fix pack 1 does not invalidate CAPTCHA answers after use. This allows remote attackers to repeatedly perform actions protected by a CAPTCHA challenge by reusing the same CAPTCHA answer.

CVE-2021-33034
HighEPSS 54%

In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, leading to writing an arbitrary value.

CVE-2021-33033
High

The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled. This leads to writing an arbitrary value.

CVE-2021-23134
High

A use-after-free vulnerability in NFC sockets in the Linux kernel before 5.12.4 allows local attackers to elevate privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability.

CVE-2021-27386
High

Zidentyfikowano podatność w panelach SIMATIC HMI Comfort oraz w systemie WinCC Runtime Advanced, która dotyczy wersji przed określonymi aktualizacjami. Problem polega na wycieku pamięci w obsłudze układu urządzenia po stronie klienta, co może prowadzić do stanu Denial-of-Service.

CVE-2021-27385
High

Zidentyfikowano podatność w różnych modelach paneli HMI SIMATIC oraz systemach SINAMICS, które mogą być narażone na atak zdalny. Atakujący może wysłać specjalnie przygotowane pakiety do obsługi układu SmartVNC, co może prowadzić do zużycia zasobów i stanu Denial-of-Service (nieskończona pętla).

CVE-2021-27383
High

Zidentyfikowano podatność w panelach SIMATIC HMI Comfort Outdoor oraz KTP Mobile, a także w systemie SIMATIC WinCC Runtime Advanced oraz różnych wersjach SINAMICS. Problem dotyczy wycieku pamięci w serwerze Tight encoder SmartVNC, co może prowadzić do stanu Denial-of-Service.

CVE-2021-25662
High

Zidentyfikowano podatność w panelach SIMATIC HMI Comfort Outdoor oraz KTP Mobile, a także w oprogramowaniu SIMATIC WinCC Runtime Advanced. Problem dotyczy nieprawidłowego obsługiwania wyjątków przez klienta SmartVNC, co może prowadzić do stanu Denial-of-Service.

CVE-2021-25661
High

Zidentyfikowano podatność w panelach SIMATIC HMI Comfort Outdoor oraz KTP Mobile, a także w SIMATIC WinCC Runtime Advanced, które są w wersjach poniżej określonych aktualizacji. Podatność ta dotyczy nieprawidłowego dostępu do pamięci w SmartVNC, co może prowadzić do awarii usługi.

CVE-2021-25660
High

Zidentyfikowano podatność w panelach SIMATIC HMI Comfort Outdoor oraz KTP Mobile, a także w SIMATIC WinCC Runtime Advanced, które są w wersjach poniżej określonych aktualizacji. Podatność ta dotyczy błędnego dostępu do pamięci w SmartVNC, co może prowadzić do awarii usługi.

CVE-2021-23892
High

Podatność CVE-2021-23892 dotyczy warunków wyścigu TOCTOU podczas instalacji Endpoint Security for Linux Threat Prevention i Firewall, co pozwala lokalnemu użytkownikowi na eskalację uprawnień do poziomu administratora. Wykorzystując tę lukę, można uruchomić dowolny kod poprzez niebezpieczne użycie przewidywalnych lokalizacji plików tymczasowych.

CVE-2021-28664
HighActively exploited

The Arm Mali GPU kernel driver allows privilege escalation or denial of service (memory corruption) because an unprivileged user can achieve read/write access to read-only pages. Affects Bifrost r0p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r8p0 through r30p0 before r31p0.

CVE-2021-28663
HighActively exploited

The Arm Mali GPU kernel driver allows privilege escalation or information disclosure because GPU memory operations are mishandled, leading to a use-after-free. Affects Bifrost r0p0 through r28p0 before r29p0, Valhall r19p0 through r28p0 before r29p0, and Midgard r4p0 through r30p0.
