CVE-2025-0725

Description

When libcurl is asked to perform automatic gzip decompression of content-encoded HTTP responses with the `CURLOPT_ACCEPT_ENCODING` option, **using zlib 1.2.0.3 or older**, an attacker-controlled integer overflow would make libcurl perform a buffer overflow.

Gravité et risque d'exploitation

CVE-2025-0725 obtient un score CVSS de 7.3/10, soit une gravité élevée. Selon le modèle EPSS, la probabilité qu'elle soit exploitée dans les 30 prochains jours est de 1.80 %, ce qui la place devant 78.2 % des CVE référencées.
