USN-5894-1: curl vulnerabilities

Severity

Medium

Vendor

VMware Tanzu

Versions Affected

• Canonical Ubuntu 16.04

Description

Harry Sintonen and Tomas Hoger discovered that curl incorrectly handled TELNET connections when the -t option was used on the command line. Uninitialized data possibly containing sensitive information could be sent to the remote server, contrary to expectations. This issue was only fixed in Ubuntu 14.04 ESM. (CVE-2021-22898, CVE-2021-22925) It was discovered that curl incorrectly handled denials when using HTTP proxies. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-43552) Update Instructions: Run `sudo pro fix USN-5894-1` to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: libcurl4-gnutls-dev - 7.47.0-1ubuntu2.19+esm7 libcurl4-openssl-dev - 7.47.0-1ubuntu2.19+esm7 libcurl3-gnutls - 7.47.0-1ubuntu2.19+esm7 libcurl4-doc - 7.47.0-1ubuntu2.19+esm7 libcurl3-nss - 7.47.0-1ubuntu2.19+esm7 libcurl4-nss-dev - 7.47.0-1ubuntu2.19+esm7 libcurl3 - 7.47.0-1ubuntu2.19+esm7 curl - 7.47.0-1ubuntu2.19+esm7 Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro
