What is CVE-2010-0734?

CVE-2010-0734 is a medium-severity denial of service vulnerability in n/a, published on 19 Mar 2010. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

content_encoding.c in libcurl 7.10.5 through 7.19.7, when zlib is enabled, does not properly restrict the amount of callback data sent to an application that requests automatic decompression, which might allow remote attackers to cause a denial of service (application crash) or have unspecified other impact by sending crafted compressed data to an application that relies on the intended data-length limit.

Weakness: CWE-264
