security advisorydenial of servicearbitrary code executionArch Linux: 202210-3 Critical Advisory On Linux-LTS Multiple Issues
The package linux-lts before version 5.15.73-3 is vulnerable to multiple issues including arbitrary code execution, information disclosure and denial of service. . Arch Linux Security Advisory ASA-202210-3 ======================================== Severity: Critical Date : 2022-10-14 CVE-ID : CVE-2022-41674 CVE-2022-42719 CVE-2022-42720 CVE-2022-42721 CVE-2022-42722 Package : linux-lts Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2802 Summary ====== The package linux-lts before version 5.15.73-3 is vulnerable to multiple issues including arbitrary code execution, information disclosure and denial of service. Resolution ========= Upgrade to 5.15.73-3. # pacman -Syu "linux-lts> =5.15.73-3" The problems have been fixed upstream in version 5.15.73. Workaround ========= None. Description ========== - CVE-2022-41674 (information disclosure) A buffer overflow flaw was found in the u8 overflow in cfg80211_update_notlisted_nontrans() in net/wireless/scan.c in the Linux kernel’s wifi subcomponent. This flaw allows a remote attacker to inject WLAN frames to crash the system or leak internal kernel information. - CVE-2022-42719 (arbitrary code execution) A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.14 could be used by remote attackers who are able to inject WLAN frames to crash the kernel and potentially execute code. - CVE-2022-42720 (arbitrary code execution) Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.14 could be used by remote attackers who are able to inject WLAN frames to trigger use-after-free conditions to potentially execute code. - CVE-2022-42721 (arbitrary code execution) A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.14 could be used by remote attackers who are able to inject WLAN frames to corrupt a linkedlist and, in turn, potentially execute code. - CVE-2022-42722 (denial of service) In the Linux kernel 5.8 through 5.19.14, remote attackers are able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices. Impact ===== A remote attacker is able to inject WLAN frames to crash the system or execute arbitrary code on the affected host.

security advisorymedium severityDoSArch Linux: 202106-42 Medium Severity: Go Package Issues
The package go before version 2:1.16.5-1 is vulnerable to multiple issues including insufficient validation, url request injection and denial of service. . Arch Linux Security Advisory ASA-202106-42 ========================================= Severity: Medium Date : 2021-06-15 CVE-ID : CVE-2021-33195 CVE-2021-33196 CVE-2021-33197 CVE-2021-33198 Package : go Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2006 Summary ====== The package go before version 2:1.16.5-1 is vulnerable to multiple issues including insufficient validation, url request injection and denial of service. Resolution ========= Upgrade to 2:1.16.5-1. # pacman -Syu "go> =2:1.16.5-1" The problems have been fixed upstream in version 1.16.5. Workaround ========= None. Description ========== - CVE-2021-33195 (insufficient validation) A security issue has been found in Go before version 1.16.5. The LookupCNAME, LookupSRV, LookupMX, LookupNS, and LookupAddr functions in net, and their respective methods on the Resolver type may return arbitrary values retrieved from DNS which do not follow the established RFC 1035 rules for domain names. If these names are used without further sanitization, for instance unsafely included in HTML, they may allow for injection of unexpected content. Note that LookupTXT may still return arbitrary values that could require sanitization before further use. - CVE-2021-33196 (denial of service) A security issue has been found in Go before version 1.16.5. Due to a pre-allocation optimization in zip.NewReader, a malformed archive which indicates it has a significant number of files can cause either a panic or memory exhaustion. - CVE-2021-33197 (url request injection) A security issue has been found in Go before version 1.16.5. ReverseProxy in net/http/httputil could be made to forward certain hop- by-hop headers, including Connection. In case the target of the ReverseProxy was itself a reverse proxy, this would let an attacker drop arbitrary headers, including those set bythe ReverseProxy.Director. - CVE-2021-33198 (denial of service) A security issue has been found in Go before version 1.16.5. The SetString and UnmarshalText methods of math/big.Rat may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents. Impact ===== An attacker could crash an application with crafted input, inject malicious and unexpected content or drop HTTP headers by posing as a reverse proxy.
