CVE-2024-11704: A double-free issue could have occurred in `sec_pkcs7_decoder_start_decrypt()` when handling an error path.

CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 39/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.91% (FIRST EPSS); higher than 60.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: firefox-esr (Debian:11) 128.7.0esr-1~deb11u1; thunderbird (Debian:11) 1:128.7.0esr-1~deb11u1; firefox-esr (Debian:12) 128.7.0esr-1~deb12u1.

Low priority for now. Upgrade to firefox-esr (Debian:11) 128.7.0esr-1~deb11u1; thunderbird (Debian:11) 1:128.7.0esr-1~deb11u1; firefox-esr (Debian:12) 128.7.0esr-1~deb12u1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A double-free issue could have occurred in `sec_pkcs7_decoder_start_decrypt()` when handling an error path. Under specific conditions, the same symmetric key could have been freed twice, potentially leading to memory corruption. This vulnerability affects Firefox < 133, Thunderbird < 133, Firefox ESR < 128.7, and Thunderbird < 128.7.
