[ASA-201811-4] curl: multiple issues
Arch Linux Security Advisory ASA-201811-4 ========================================= Severity: High Date : 2018-11-06 CVE-ID : CVE-2018-16840 CVE-2018-16842 Package : curl Type : multiple issues Remote : Yes Link : Summary ======= The package curl before version 7.62.0-1 is vulnerable to multiple issues including arbitrary code execution and information disclosure. Resolution ========== Upgrade to 7.62.0-1. # pacman -Syu "curl>=7.62.0-1" The problems have been fixed upstream in version 7.62.0. Workaround ========== None. Description =========== - CVE-2018-16840 (arbitrary code execution) A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct. - CVE-2018-16842 (information disclosure) Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service. This display function formats the output to wrap at 80 columns. The wrap logic is however flawed, so if a single word in the message is itself longer than 80 bytes the buffer arithmetic calculates the remainder wrong and will end up reading behind the end of the buffer. Impact ====== A malicious remote server could execute arbitrary commands by closing the client initialized with easy handlers. A malicious local user could disclose information and crash the application if invalid flags were passed. References ==========
