Package : curl
Version : 7.64.0-4+deb10u9
CVE ID : CVE-2023-27534
curl was affected by a path traversal vulnerability.
SFTP implementation causes the tilde (~) character to be wrongly
replaced when used as a prefix in the first path element,
in addition to its intended use as the first element to indicate
a path relative to the user's home directory. Attackers can exploit
this flaw to bypass filtering or execute arbitrary code by
crafting a path like /~2/foo while accessing a server with
a specific user.
For Debian 10 buster, this problem has been fixed in version
7.64.0-4+deb10u9.
We recommend that you upgrade your curl packages.
